Nomenumbra has discovered a vulnerability in PHP-AGTC membership system, which can be exploited by malicious users to conduct script insertion attacks.

Input passed to the "useremail" parameter in adduser.php isn't properly sanitised before being used. This can be exploited to inject arbitrary HTML and script code, which will be executed in an administrator's browser session in context of an affected site when the malicious user data is viewed via admin.php.

The vulnerability has been confirmed in version 1.1a. Other versions may also be affected.
