SECUNIA ADVISORY ID:

VERIFY ADVISORY:
http://secunia.com/advisories/35236/
DESCRIPTION:
Jacques Copeau has reported a vulnerability in WoltLab Burning Board,
which can be exploited by malicious users to conduct cross-site
scripting attacks.
The vulnerability is caused due to the application not properly
sanitising uploaded image files. This can be exploited to execute
arbitrary HTML and script code in a user's Internet Explorer session
in the context of an affected site by uploading malformed image
files, which are interpreted by the user's browser as having a
"text/html" MIME type.
The vulnerability is reported in version 3.0.8. Other versions may
also be affected.
SOLUTION:
Filter malicious characters and character sequences in a web proxy.
