Title
PaperCut NG/MF: Remote Code Execution via Scripting Subsystem
Summary
A vulnerability exists in the PaperCut NG/MF platform's device-scripting functionality due to insufficient sanitization and access restrictions within the embedded execution engine. An authenticated user with administrative access to the management interface can supply a malicious script that escapes the runtime sandbox.
A successful execution enables an attacker to run unauthorized operating system commands with administrative privileges on the host operating system.

Title
PaperCut NG/MF: User enumeration via timing attack
Summary
PaperCut NG/MF contains an observable timing discrepancy in its authentication component. An unauthenticated remote attacker can exploit this vulnerability to perform username enumeration by measuring response times during login attempts. The system executes a password hash comparison only when a valid account is supplied, creating a measurable timing oracle that reveals account existence.

Title
PaperCut NG/MF: Path Traversal in Shared Account Synchronization
Summary
An issue was discovered in the Shared Account Synchronization component of PaperCut MF (version 25.0.4). The application allows administrative users to configure a source path for account data synchronization.
Due to a lack of proper path validation and sanitization, an authenticated user with administrative privileges can specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files.
When the synchronization process is triggered, the application attempts to parse the contents of the specified file, subsequently exposing the data within the application's account management interface. This vulnerability could lead to the disclosure of sensitive system information or configuration details, depending on the permissions of the service account under which the application is running.

Title
PaperCut MF: Card truncation on HP readers
Summary
A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions involving dropped packets and out-of-order sequence counters, the server may incorrectly process fragmented data chunks. If a sequence reset notification fails to reach the server, the server may reject the initial data chunk while erroneously accepting subsequent chunks before a connection reset completes.
This leads to the registration of a truncated badge ID string. While this typically results in an authentication failure, the vulnerability is compounded in environments utilizing custom badge-ID post-processing scripts. In such configurations, the truncated string may be transformed into a valid ID belonging to a different user, leading to unauthorized session establishment (Incorrect User Login) on the device.

Title
Session hijacking in PaperCut NG/MF embedded application for Konica Minolta devices
Summary
The PaperCut NG/MF (specifically, the embedded application for Konica Minolta devices) is vulnerable to session hijacking. The PaperCut NG/MF Embedded application is a software interface that runs directly on the touch screen of a multi-function device.
It was internally discovered that the communication channel between the embedded application and the server was insecure, which could leak data including sensitive information that may be used to mount an attack on the device. Such an attack could potentially be used to steal data or to perform a phishing attack on the end user.

Title
Multiple cross-site scripting (XSS) vulnerabilities in PaperCut NG/MF
Summary
Multiple cross-site scripting (XSS) vulnerabilities in PaperCut NG/MF before 25.0.10 allow authenticated administrator users to inject arbitrary web script or HTML code via different UI fields. This could be used to compromise other admininistrator's sessions or perform unauthorized actions via the administrator's authenticated context (e.g. requires an active login session).

CVE-2023-2533 (GCVE-0-2023-2533)
Vulnerability from nvd – Published: 2023-06-20 14:45 – Updated: 2025-10-21 23:05Title
PaperCut MF/NG 22.0.10 (Build 65996 2023-03-27) - Remote code execution via CSRF
Summary
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in
PaperCut NG/MF, which, under specific conditions, could potentially enable
an attacker to alter security settings or execute arbitrary code. This could
be exploited if the target is an admin with a current login session. Exploiting
this would typically involve the possibility of deceiving an admin into clicking
a specially crafted malicious link, potentially leading to unauthorized changes.

Title
PaperCut NG/MF: Remote Code Execution via Scripting Subsystem
Summary
A vulnerability exists in the PaperCut NG/MF platform's device-scripting functionality due to insufficient sanitization and access restrictions within the embedded execution engine. An authenticated user with administrative access to the management interface can supply a malicious script that escapes the runtime sandbox.
A successful execution enables an attacker to run unauthorized operating system commands with administrative privileges on the host operating system.

PaperCut NG/MF: User enumeration via timing attack
Summary
PaperCut NG/MF contains an observable timing discrepancy in its authentication component. An unauthenticated remote attacker can exploit this vulnerability to perform username enumeration by measuring response times during login attempts. The system executes a password hash comparison only when a valid account is supplied, creating a measurable timing oracle that reveals account existence.

Title
PaperCut NG/MF: Path Traversal in Shared Account Synchronization
Summary
An issue was discovered in the Shared Account Synchronization component of PaperCut MF (version 25.0.4). The application allows administrative users to configure a source path for account data synchronization.
Due to a lack of proper path validation and sanitization, an authenticated user with administrative privileges can specify arbitrary file paths on the local file system. This allows for the enumeration of directory structures and the unauthorized reading of sensitive text-based configuration or system files.
When the synchronization process is triggered, the application attempts to parse the contents of the specified file, subsequently exposing the data within the application's account management interface. This vulnerability could lead to the disclosure of sensitive system information or configuration details, depending on the permissions of the service account under which the application is running.

Title
PaperCut MF: Card truncation on HP readers
Summary
A race condition exists in PaperCut MF when processing badge-swipe data from certain HP multifunction devices. Under specific network conditions involving dropped packets and out-of-order sequence counters, the server may incorrectly process fragmented data chunks. If a sequence reset notification fails to reach the server, the server may reject the initial data chunk while erroneously accepting subsequent chunks before a connection reset completes.
This leads to the registration of a truncated badge ID string. While this typically results in an authentication failure, the vulnerability is compounded in environments utilizing custom badge-ID post-processing scripts. In such configurations, the truncated string may be transformed into a valid ID belonging to a different user, leading to unauthorized session establishment (Incorrect User Login) on the device.

Title
Session hijacking in PaperCut NG/MF embedded application for Konica Minolta devices
Summary
The PaperCut NG/MF (specifically, the embedded application for Konica Minolta devices) is vulnerable to session hijacking. The PaperCut NG/MF Embedded application is a software interface that runs directly on the touch screen of a multi-function device.
It was internally discovered that the communication channel between the embedded application and the server was insecure, which could leak data including sensitive information that may be used to mount an attack on the device. Such an attack could potentially be used to steal data or to perform a phishing attack on the end user.

PaperCut MF/NG 22.0.10 (Build 65996 2023-03-27) - Remote code execution via CSRF
Summary
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in
PaperCut NG/MF, which, under specific conditions, could potentially enable
an attacker to alter security settings or execute arbitrary code. This could
be exploited if the target is an admin with a current login session. Exploiting
this would typically involve the possibility of deceiving an admin into clicking
a specially crafted malicious link, potentially leading to unauthorized changes.
