Description:
A vulnerability has been reported in vBulletin, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "redirect" parameter in modcp/index.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.
NOTE: Reportedly, this can be exploited to inject and execute arbitrary PHP code on an affected system, but requires that the administrator is logged in or logs in e.g. when following a specially crafted link.
The vulnerability is reported in versions 3.7.1 PL1, 3.6.10 PL1, and all previous 3.x versions.
Solution:
Update to version 3.7.1 PL2 or 3.6.10 PL2.
