CGI::Simple versions before 1.282 for Perl has a HTTP response splitting flaw This vulnerability is a confirmed HTTP response splitting flaw in CGI::Simple that allows HTTP response header injection, which can be used for reflected XSS or open redirect under certain conditions.
Although some validation exists, it can be bypassed using URL-encoded values, allowing an attacker to inject untrusted content into the response via query parameters.
As a result, an attacker can inject a line break (e.g. %0A) into the parameter value, causing the server to split the HTTP response and inject arbitrary headers or even an HTML/JavaScript body, leading to reflected cross-site scripting (XSS), open redirect or other attacks.
The issue documented in CVE-2010-4410 https://www.cve.org/CVERecord?id=CVE-2010-4410 is related but the fix was incomplete.
Impact
By injecting %0A (newline) into a query string parameter, an attacker can:
* Break the current HTTP header * Inject a new header or entire body * Deliver a script payload that is reflected in the server’s response That can lead to the following attacks:
* reflected XSS * open redirect * cache poisoning * header manipulation

Ein entfernter, anonymer Angreifer kann eine Schwachstelle in cPanel cPanel/WHM ausnutzen, um eine HTTP-Response-Header-Injection durchzuführen, wodurch er Cross-Site-Scripting (XSS) und Open-Redirect-Angriffe durchführen und den Cache oder den Header manipulieren kann.
