Description:
David Sopas Ferreira has discovered a vulnerability in Private Message System, which can be exploited by malicious people to conduct cross-site scripting attacks.
The vulnerability is caused due to missing validation of input supplied to the "page" parameter in "index.php". This can be exploited to execute arbitrary HTML or script code in a user's browser session in the context of an affected site.
Successful exploitation can result in disclosure of various information (e.g. cookie-based authentication information) associated with the site running Private Message System or inclusion of malicious content, which the user thinks is part of the real website.
Example:
http://[vulnerable_system]/index.php?page="><script>alert(document.domain);</script>
The vulnerability has been reported in version 2.2.9 and prior.
Solution:
Update to version 2.3.0.
