DESCRIPTION:
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:
Filter malicious characters and character sequences in a web proxy.
Restrict access to trusted users only.
