Title
MISP Reflected Cross-Site Scripting via Unsanitized Analyst Data Seed Parameter
Summary
MISP contains a reflected cross-site scripting (XSS) vulnerability in the analyst data notes panel. The seed path parameter, supplied by the user via the URL, was passed directly into inline JavaScript within the rendered HTML response without any sanitization or type enforcement.
An attacker who can convince an authenticated MISP user to navigate to a crafted URL (for example, via a phishing link) can inject arbitrary JavaScript that executes in the victim's browser context. This may allow the attacker to read session tokens, manipulate the page, or perform actions on behalf of the victim.
Preconditions:
- The victim must be authenticated to MISP and access the analyst data view for an attribute or object.
- The attacker must supply a malicious seed value in the URL path.
Impact:
- Execution of arbitrary JavaScript in the victim's browser session.
- Potential theft of session credentials or sensitive data visible in the page.
- Manipulation of the analyst data interface.
Affected: MISP versions prior to the fix (commit 58925dbf0, post v2.5.48).

fix: [security] Cast the analyst data seed to an integer | 7e384946a0fb… |
Fix summary
The vulnerability is remediated by enforcing integer type on the seed parameter at both the controller layer and the view/template layer. Casting the value to an integer ensures that any non-numeric input (including script payloads) is neutralized before it reaches the inline JavaScript context, eliminating the injection vector.
Patch summary
In AttributesController.php and ObjectsController.php, the seed value set for the view is now cast to an integer with a fallback to a random integer if the cast yields zero. In the two analyst data view templates (generic_simple.ctp and thread.ctp), the seed variable is similarly cast to an integer before use in inline script, replacing the previous logic that only checked for emptiness without type enforcement.
CVSS rationale
AV:N - exploitable over the network via a crafted URL. AC:L - no race conditions or special conditions; a simple URL with a malicious seed suffices. AT:N - no prior manipulation of the target system needed. PR:L - MISP is an authenticated platform; the attacker needs at least a low-privilege account or must target an authenticated user. UI:A - the victim must actively navigate to the crafted URL. VC/VI/VA:N - the server-side confidentiality, integrity, and availability are not directly impacted. SC:L - the victim's browser session data (cookies, tokens) can be read. SI:L - the victim's page content can be modified. SA:N - no impact on security authority.
Weakness rationale
- CWE-79 The user-supplied seed parameter was reflected into inline JavaScript in the HTML response without sanitization or type coercion, allowing script injection. This is a textbook reflected XSS.
Attack pattern rationale
- CAPEC-1 The attacker supplies a malicious value in a URL parameter (seed), which the server reflects unmodified into inline JavaScript in the HTTP response. The victim's browser executes the injected script. This matches the reflected XSS pattern precisely. No uncertainty in this mapping.
Assumptions to verify
- MISP requires user authentication to access the analyst data views; PR:L assumes a low-privilege authenticated account is sufficient for the attacker to craft or deliver the malicious URL.
- The exact fixed version number is not stated in the patch; the fix commit is 32 commits after the v2.5.48 tag, so the fixed version is presumed to be a release after 2.5.48.
- The UI:A rating assumes the victim must click a link or navigate to the crafted URL; if the seed could be injected via a different vector requiring no user interaction, UI could be None.
- CAPEC-1 (Reflected XSS) is selected as the closest match; the injection occurs server-side into the HTML response, distinguishing it from DOM-based XSS (CAPEC-64).

Title
MISP Reflected XSS in Taxonomy Tag Confirmation Forms
Summary
MISP contains a reflected cross-site scripting (XSS) vulnerability in the legacy taxonomy tag management confirmation forms (add tag and disable tag).
The affected forms echoed a user-supplied tag name value from the request unescaped into the rendered HTML output. An attacker who can induce a site administrator to visit a crafted URL containing a malicious tag name parameter can execute arbitrary JavaScript in the administrator's browser session.
Preconditions:
- The target must be running a MISP instance with the legacy taxonomy tag confirmation views enabled.
- The victim must be an authenticated site administrator.
- The victim must navigate to the attacker-crafted URL (e.g., via a phishing link).
Security impact:
- Execution of arbitrary client-side script in the context of the administrator's browser.
- Potential theft of session tokens, CSRF tokens, or other sensitive data accessible from the page.
- Potential for performing privileged actions on behalf of the administrator within the MISP interface.
Affected versions: <2.5.48.

fix: [security] Escape the tag name on the taxonomy tag | 0255a5f82ee8… |
Fix summary
The vulnerability is remediated by HTML-encoding the user-supplied tag name value before it is interpolated into the confirmation form description text. This ensures that any HTML metacharacters in the input are rendered as inert text rather than executable markup, neutralizing the reflected XSS vector.
Patch summary
Two view template files (app/View/Taxonomies/add_tag.ctp and app/View/Taxonomies/disable_tag.ctp) are modified. In each file, the raw request data value $this->request->data['Taxonomy']['name'] is wrapped with CakePHP's h() HTML-encoding helper function before being passed to the translation string that renders the confirmation description. This is a one-line change per file, adding the h() wrapper around the previously unescaped variable.
CVSS rationale
AV:N - the vulnerability is exploitable over the network via a crafted URL. AC:L - no race conditions or special conditions; simply visiting a crafted URL triggers the XSS. AT:N - no attack target manipulation required. PR:N - the attacker does not need authentication; they craft a URL for the admin to visit. UI:A - the administrator must actively navigate to the malicious URL. VC:L - the XSS can read session cookies and page data in the admin's browser. VI:L - the XSS can perform actions on behalf of the admin within the MISP interface. VA:N - no availability impact. SC/SI/SA:N - the impact is confined to the victim's browser session; no secondary system impact is evidenced.
Weakness rationale
- CWE-79 The patch directly addresses a reflected XSS: user-controlled input from the request is echoed into HTML output without encoding. The fix applies HTML entity encoding (h() helper), which is the canonical remediation for CWE-79.
Attack pattern rationale
- CAPEC-63 The commit message explicitly states the tag name is 'echoed from the URL unescaped, a reflected XSS.' The attacker supplies a malicious value via a URL parameter, the application reflects it into the HTML response without encoding, and the script executes in the victim's browser. This is a textbook reflected XSS pattern matching CAPEC-63 exactly.
Assumptions to verify
- The tag v2.5.48 is assumed to be the first release containing the fix based on the tag_version_boundary metadata showing 44 commits after the fix commit; the exact release version that first shipped the fix is not explicitly stated.
- The vulnerability requires the legacy taxonomy tag confirmation views to be in use; if MISP has migrated to a different UI for taxonomy management, the attack surface may not be reachable.
- PR:N is assumed because the attacker does not need their own MISP account; they only need to deliver a crafted URL to an authenticated admin. If the form is only reachable via authenticated session and the parameter cannot be injected via URL for unauthenticated users, PR could be elevated.
- The Co-Authored-By line references an AI tool (Claude Opus 5.5); this is not credited as a human contributor per standard CVE credit practices.
- CAPEC-63 is selected as the closest match; the exact CAPEC taxonomy does not have a more specific entry for reflected XSS in server-rendered template engines.

Title
MISP Stored Cross-Site Scripting via Unvalidated Galaxy Icon Field in Correlation Graph
Summary
MISP contains a stored cross-site scripting (XSS) vulnerability in the galaxy icon handling path. The icon field of a galaxy object was persisted without any server-side validation through the galaxy add, edit, and sync/import capture endpoints. The stored value was subsequently concatenated directly into HTML markup by the D3-based correlation graph rendering scripts (both the default and Overmind themes) using the .html() method.
A user holding the perm_galaxy_editor permission, which is granted to the stock User role, could store arbitrary HTML or JavaScript in the icon field. Any other user who opened the correlation graph of an event containing a cluster belonging to that galaxy would have the injected script executed in their browser session.
Impact:
- Arbitrary script execution in the context of the victim's MISP session
- Potential theft of session credentials, manipulation of displayed data, or initiation of actions on behalf of the victim
- Affects both the default and Overmind UI themes
Affected versions: <2.5.48

fix: [security] Galaxy icons are icon names, and the | 382869c811e8… |
Fix summary
The vulnerability is remediated by enforcing strict input validation on the galaxy icon field so that only valid Font Awesome icon names (lowercase alphanumeric characters and dashes) are accepted at write time. The sync/import capture path discards any icon value that does not conform. The correlation graph JSON generation falls back to a safe default icon for any previously stored invalid value. On the client side, both correlation graph scripts now set the icon as a CSS class attribute rather than injecting it as raw HTML, and apply an additional regex sanitization pass. The asset cache-busting version is incremented to ensure browsers load the corrected scripts.
Patch summary
Added a static isValidIconName() method and a regex constant (ICON_NAME_PATTERN) to the Galaxy model, plus a model-level validation rule restricting the icon field to lowercase letters, digits, and dashes. The captureGalaxy() method now blanks out any icon value that fails validation before persistence. CorrelationGraphTool::__createNode() now checks the icon against the validator and substitutes 'globe' for invalid stored values. Both correlation-graph.js and correlation-graphOvermind.js were changed from .html() string concatenation to .attr('class', ...) with a regex strip of non-conforming characters. AppController asset query version bumped from 225 to 226. A new PHPUnit test file (GalaxyIconNameTest.php) validates the icon name rule against known-good and known-bad payloads including the originally reported XSS vector.
CVSS rationale
AV:N: exploited over the network via the MISP web interface. AC:L: no race conditions or special timing; simply set the icon field and wait for a victim to view the graph. AT:N: no manipulation of the attack target required. PR:L: requires an authenticated user with perm_galaxy_editor, which is the default stock User role. UI:A: the victim must actively open the correlation graph of an event containing the affected galaxy cluster. VC/VI/VA:N: the server-side application is not directly compromised; the impact is on the victim's browser session. SC:H: script execution in the victim's session can read cookies, tokens, and sensitive page data. SI:H: the attacker can modify the victim's view, inject content, or trigger actions. SA:N: no availability impact on the system.
Weakness rationale
- CWE-79 The galaxy icon field was stored without validation and later rendered into the DOM via D3 .html(), allowing an attacker to inject and execute arbitrary script in the victim's browser. This is a textbook stored XSS.
- CWE-20 The root enabler is the absence of any server-side validation on the icon field at write time (add, edit, capture). The field accepted arbitrary strings including HTML markup, which was the precondition for the XSS.
Attack pattern rationale
- CAPEC-1 The attack pattern is a stored XSS: an authenticated user with galaxy editor permission injects a script payload into a persistent data field (galaxy icon), which is later rendered unsanitized in another user's browser via the correlation graph. CAPEC-1 is the closest and most direct match. No more specific CAPEC entry for stored XSS via a data field rendered by a graphing library exists in the CAPEC catalog, so CAPEC-1 is the best available mapping.
Assumptions to verify
- The affected version boundary is inferred from the tag_version_boundary metadata indicating the fix commit precedes v2.5.48 by 20 commits; no explicit 'fixed in' version is stated in the patch itself.
- The perm_galaxy_editor permission is assumed to be granted to the stock User role as stated in the commit message; the exact role-permission mapping was not independently verified from the patch.
- CAPEC-1 is the closest available mapping; no CAPEC entry specifically describes stored XSS via a graph-rendering library data field, so the general Cross Site Scripting pattern is used.
- CVSS UI:A assumes the victim must navigate to the correlation graph view of a specific event; if the graph is auto-loaded on a commonly visited page, UI could be lowered to Passive.
- The Co-Authored-By line references an AI assistant (Claude Fable 5.1); it is recorded as a tool credit rather than a human remediation developer.

"patchSummary": "Added a static isValidIconName() method and a regex constant (ICON_NAME_PATTERN) to the Galaxy model, plus a model-level validation rule restricting the icon field to lowercase letters, digits, and dashes. The captureGalaxy() method now blanks out any icon value that fails validation before persistence. CorrelationGraphTool::__createNode() now checks the icon against the validator and substitutes \u0027globe\u0027 for invalid stored values. Both correlation-graph.js and correlation-graphOvermind.js were changed from .html() string concatenation to .attr(\u0027class\u0027, ...) with a regex strip of non-conforming characters. AppController asset query version bumped from 225 to 226. A new PHPUnit test file (GalaxyIconNameTest.php) validates the icon name rule against known-good and known-bad payloads including the originally reported XSS vector.",

Title
MISP Stored Cross-Site Scripting via JavaScript URL in Galaxy Cluster Source Field
Summary
MISP renders the source field of a Galaxy Cluster as a clickable hyperlink whenever the stored value passes PHP's FILTER_VALIDATE_URL validation. Because FILTER_VALIDATE_URL accepts the javascript: URI scheme, a user with galaxy editor privileges on the local instance or on a synced instance could store a javascript: URL as the cluster source.
When another user views the affected Galaxy Cluster and clicks the rendered link, the embedded script executes in the victim's browser context, enabling session hijacking, data exfiltration, or actions performed on behalf of the victim.
Preconditions:
- Attacker must hold galaxy editor privileges (local or via sync).
- Victim must view the affected cluster and click the malicious link.
Impact:
- Stored cross-site scripting (XSS) in the victim's browser.
- Potential session theft, credential harvesting, or unauthorized actions within the MISP application.
Affected: <2.5.48.

fix: [security] Link a galaxy cluster source only when it is | b68dbd672692… |
Fix summary
The fix restricts the rendering of the Galaxy Cluster source field as a hyperlink to only http:// and https:// URLs by adding a regular-expression check (preg_match for ^https?://) in addition to the existing FILTER_VALIDATE_URL validation. This prevents javascript: and other non-HTTP URI schemes from being rendered as clickable links, eliminating the stored XSS vector. The change is applied consistently in both the default theme and the Overmind theme.
Patch summary
Two view templates are modified. In app/View/GalaxyClusters/view.ctp, the source value is extracted into a local variable and the conditional for rendering an anchor tag now requires both FILTER_VALIDATE_URL and a preg_match against /^https?:\/\//i. In app/View/Themed/Overmind/Elements/GalaxyClusters/View/galaxy_clusters_general.ctp, the same preg_match guard is added to the existing FILTER_VALIDATE_URL check. Net effect: only http(s) URLs produce a clickable link; all other values (including javascript:) are rendered as plain escaped text.
CVSS rationale
AV:N – MISP is a web application accessed over the network. AC:L – no race conditions or special environment needed; storing a javascript: URL is straightforward. AT:N – no manipulation of the attack target required. PR:L – attacker needs galaxy editor privileges (authenticated, non-admin role). UI:A – victim must click the malicious link for script execution. VC/VI/VA:N – the MISP server itself is not directly compromised; impact is on the victim's browser. SC:H – attacker can read cookies, session tokens, and manipulate the DOM in the victim's session. SI:H – attacker can perform actions on behalf of the victim within MISP. SA:N – no direct compromise of the application's security controls or system integrity.
Weakness rationale
- CWE-79 The application renders user-controlled data (the galaxy cluster source field) into an HTML anchor tag without restricting the URI scheme to safe values. Although output is HTML-escaped via h(), the href attribute still accepts javascript: URIs, resulting in stored XSS. CWE-79 is the narrowest defensible mapping.
Attack pattern rationale
- CAPEC-64 The attack pattern involves storing a malicious payload (a javascript: URL) in a persistent data field (galaxy cluster source) that is later rendered in a web page, executing script in the victim's browser upon interaction. This is a textbook persistent/stored XSS. CAPEC-64 is the closest and most precise match in the CAPEC catalog.
Assumptions to verify
- The affected version boundary is inferred from the tag_version_boundary metadata (v2.5.48, 26 commits after fix); the exact first affected release is not stated in the patch.
- PR:L assumes galaxy editor privileges are a non-admin, role-based permission; the exact privilege model is not detailed in the patch.
- UI:A assumes the victim must actively click the rendered link; passive rendering without click does not execute the script.
- The CAPEC-64 mapping is the closest available pattern for stored XSS; no CAPEC specifically covers URI-scheme-based stored XSS, so CAPEC-64 is the best fit.
- The Co-Authored-By line references an AI assistant; it is credited as a tool rather than a human remediation developer.

Mitigation MIT-4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
- Examples of libraries and frameworks that make it easier to generate properly encoded output include Microsoft's Anti-XSS library, the OWASP ESAPI Encoding module, and Apache Wicket.
Mitigation
Implementation
Architecture and Design
- Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages. Study all expected communication protocols and data representations to determine the required encoding strategies.
- For any data that will be output to another web page, especially any data that was received from external inputs, use the appropriate encoding on all non-alphanumeric characters.
- Parts of the same output document may require different encodings, which will vary depending on whether the output is in the:
- etc. Note that HTML Entity Encoding is only appropriate for the HTML body.
- Consult the XSS Prevention Cheat Sheet [REF-724] for more details on the types of encoding and escaping that are needed.
- HTML body
- Element attributes (such as src="XYZ")
- URIs
- JavaScript sections
- Cascading Style Sheets and style property
Mitigation MIT-6
Architecture and Design
Implementation
Strategy: Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
Mitigation MIT-15
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.
Mitigation MIT-27
Architecture and Design
Strategy: Parameterization
If available, use structured mechanisms that automatically enforce the separation between data and code. These mechanisms may be able to provide the relevant quoting, encoding, and validation automatically, instead of relying on the developer to provide this capability at every point where output is generated.
Mitigation MIT-30.1
Implementation
Strategy: Output Encoding
- Use and specify an output encoding that can be handled by the downstream component that is reading the output. Common encodings include ISO-8859-1, UTF-7, and UTF-8. When an encoding is not specified, a downstream component may choose a different encoding, either by assuming a default encoding or automatically inferring which encoding is being used, which can be erroneous. When the encodings are inconsistent, the downstream component might treat some character or byte sequences as special, even if they are not special in the original encoding. Attackers might then be able to exploit this discrepancy and conduct injection attacks; they even might be able to bypass protection mechanisms that assume the original encoding is also being used by the downstream component.
- The problem of inconsistent output encodings often arises in web pages. If an encoding is not specified in an HTTP header, web browsers often guess about which encoding is being used. This can open up the browser to subtle XSS attacks.
Mitigation MIT-43
Implementation
With Struts, write all data from form beans with the bean's filter attribute set to true.
Mitigation MIT-31
Implementation
Strategy: Attack Surface Reduction
To help mitigate XSS attacks against the user's session cookie, set the session cookie to be HttpOnly. In browsers that support the HttpOnly feature (such as more recent versions of Internet Explorer and Firefox), this attribute can prevent the user's session cookie from being accessible to malicious client-side scripts that use document.cookie. This is not a complete solution, since HttpOnly is not supported by all browsers. More importantly, XmlHttpRequest and other powerful browser technologies provide read access to HTTP headers, including the Set-Cookie header in which the HttpOnly flag is set.
Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- When dynamically constructing web pages, use stringent allowlists that limit the character set based on the expected value of the parameter in the request. All input should be validated and cleansed, not just parameters that the user is supposed to specify, but all data in the request, including hidden fields, cookies, headers, the URL itself, and so forth. A common mistake that leads to continuing XSS vulnerabilities is to validate only fields that are expected to be redisplayed by the site. It is common to see data from the request that is reflected by the application server or the application that the development team did not anticipate. Also, a field that is not currently reflected may be used by a future developer. Therefore, validating ALL parts of the HTTP request is recommended.
- Note that proper output encoding, escaping, and quoting is the most effective solution for preventing XSS, although input validation may provide some defense-in-depth. This is because it effectively limits what will appear in output. Input validation will not always prevent XSS, especially if you are required to support free-form text fields that could contain arbitrary characters. For example, in a chat application, the heart emoticon ("<3") would likely pass the validation step, since it is commonly used. However, it cannot be directly inserted into the web page because it contains the "<" character, which would need to be escaped or otherwise handled. In this case, stripping the "<" might reduce the risk of XSS, but it would produce incorrect behavior because the emoticon would not be recorded. This might seem to be a minor inconvenience, but it would be more important in a mathematical forum that wants to represent inequalities.
- Even if you make a mistake in your validation (such as forgetting one out of 100 input fields), appropriate encoding is still likely to protect you from injection-based attacks. As long as it is not done in isolation, input validation is still a useful technique, since it may significantly reduce your attack surface, allow you to detect some attacks, and provide other security benefits that proper encoding does not address.
- Ensure that you perform input validation at well-defined interfaces within the application. This will help protect the application even if a component is reused or moved elsewhere.
Mitigation MIT-21
Architecture and Design
Strategy: Enforcement by Conversion
When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
Mitigation MIT-29
Operation
Strategy: Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
Mitigation MIT-16
Operation
Implementation
Strategy: Environment Hardening
When using PHP, configure the application so that it does not use register_globals. During implementation, develop the application so that it does not rely on this feature, but be wary of implementing a register_globals emulation that is subject to weaknesses such as CWE-95, CWE-621, and similar issues.
CAPEC-209: XSS Using MIME Type Mismatch
An adversary creates a file with scripting content but where the specified MIME type of the file is such that scripting is not expected. The adversary tricks the victim into accessing a URL that responds with the script file. Some browsers will detect that the specified MIME type of the file does not match the actual type of its content and will automatically switch to using an interpreter for the real content type. If the browser does not invoke script filters before doing this, the adversary's script may run on the target unsanitized, possibly revealing the victim's cookies or executing arbitrary script in their browser.
CAPEC-588: DOM-Based XSS
This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is inserted into the client-side HTML being parsed by a web browser. Content served by a vulnerable web application includes script code used to manipulate the Document Object Model (DOM). This script code either does not properly validate input, or does not perform proper output encoding, thus creating an opportunity for an adversary to inject a malicious script launch a XSS attack. A key distinction between other XSS attacks and DOM-based attacks is that in other XSS attacks, the malicious script runs when the vulnerable web page is initially loaded, while a DOM-based attack executes sometime after the page loads. Another distinction of DOM-based attacks is that in some cases, the malicious script is never sent to the vulnerable web server at all. An attack like this is guaranteed to bypass any server-side filtering attempts to protect users.
CAPEC-591: Reflected XSS
This type of attack is a form of Cross-Site Scripting (XSS) where a malicious script is "reflected" off a vulnerable web application and then executed by a victim's browser. The process starts with an adversary delivering a malicious script to a victim and convincing the victim to send the script to the vulnerable web application.
CAPEC-592: Stored XSS
An adversary utilizes a form of Cross-site Scripting (XSS) where a malicious script is persistently "stored" within the data storage of a vulnerable web application as valid input.
CAPEC-63: Cross-Site Scripting (XSS)
An adversary embeds malicious scripts in content that will be served to web browsers. The goal of the attack is for the target software, the client-side browser, to execute the script with the users' privilege level. An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute code and scripts. Web browsers, for example, have some simple security controls in place, but if a remote attacker is allowed to execute scripts (through injecting them in to user-generated content like bulletin boards) then these controls may be bypassed. Further, these attacks are very difficult for an end user to detect.
CAPEC-85: AJAX Footprinting
This attack utilizes the frequent client-server roundtrips in Ajax conversation to scan a system. While Ajax does not open up new vulnerabilities per se, it does optimize them from an attacker point of view. A common first step for an attacker is to footprint the target environment to understand what attacks will work. Since footprinting relies on enumeration, the conversational pattern of rapid, multiple requests and responses that are typical in Ajax applications enable an attacker to look for many vulnerabilities, well-known ports, network locations and so on. The knowledge gained through Ajax fingerprinting can be used to support other attacks, such as XSS.
