Jessica Hope has reported a vulnerability in WoltLab Burning Board, which can be exploited by malicious people to disclose potentially sensitive information or to conduct cross-site scripting attacks.
Input passed via e.g. the "page" and "form" parameters to PHP files using the WoltLab Community Framework (WCF) to process requests is not properly sanitised before being returned to the user in an error message. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site and to disclose installation path names.
The vulnerability is reported in WCF version 1.0.6, included in WoltLab Burning Board 3.0.5. Other versions may also be affected.
Solution: Reportedly fixed in WCF 1.0.6 pl1.
