XRMS CRM "msg" Cross Site Scripting Vulnerability

Monday, 3 March 2008

Description:
vijayv has reported a vulnerability in XRMS CRM, which can be exploited by malicious people to conduct cross-site scripting attacks.

Input passed to the "msg" parameter in /admin/users/self.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Successful exploitation requires that the target user is logged-in to the application.

Solution:
Edit the source code to ensure that input is properly sanitised.
