SA21483

VERIFY ADVISORY:
http://secunia.com/advisories/21483/

CRITICAL:
Not critical

IMPACT:
Exposure of system information

WHERE:
>From remote

SOFTWARE:
XennoBB 2.x
http://secunia.com/product/11262/

DESCRIPTION:
Chris Boulton has discovered a weakness in XennoBB, which can be
exploited by malicious people to disclose system information.

Input passed to the "category" parameter in profile.php isn't
properly sanitised before being used to view available avatars. This
can be exploited to list images in arbitrary locations via directory
traversal attacks.

The weakness has been confirmed in version 2.1.0. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.

PROVIDED AND/OR DISCOVERED BY:
