Name of the Vulnerable Software and Affected Versions SquirrelMail versions 1.4.22 and earlier SquirrelMail versions 1.5.x through 1.5.2

Description A security issue was discovered due to improper handling of RCDATA and RAWTEXT type elements, allowing the built-in sanitization mechanism to be bypassed. This can lead to the execution of malicious script content from HTML e-mail within the application context via crafted use of elements such as NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA.

Recommendations For SquirrelMail versions 1.4.22 and earlier, update to a version later than 1.4.22 to resolve the issue. For SquirrelMail versions 1.5.x through 1.5.2, update to a version later than 1.5.2 to resolve the issue. As a temporary workaround, consider restricting the use of potentially vulnerable elements such as NOEMBED, NOFRAMES, NOSCRIPT, or TEXTAREA until a patch is available.
