Wsn · Wsn Forum · CVE-2008-3555
**Name of the Vulnerable Software and Affected Versions**
WSN Forum versions 4.1.43 and earlier
Gallery versions 4.1.30 and earlier
Knowledge Base (WSNKB) versions 4.1.36 and earlier
Links versions 4.1.44 and earlier
Classifieds versions prior to 4.1.30
**Description**
A directory traversal issue allows remote attackers to include and execute arbitrary local files via a .. (dot dot) in the `TID` parameter. This can be exploited by uploading a file, such as a .jpg file, containing PHP sequences.
**Recommendations**
For WSN Forum versions 4.1.43 and earlier, update to a version later than 4.1.43.
For Gallery versions 4.1.30 and earlier, update to a version later than 4.1.30.
For Knowledge Base (WSNKB) versions 4.1.36 and earlier, update to a version later than 4.1.36.
For Links versions 4.1.44 and earlier, update to a version later than 4.1.44.
For Classifieds versions prior to 4.1.30, update to version 4.1.30 or later.
As a temporary workaround, consider restricting access to the `TID` parameter in the affected `index.php` file until a patch is available.
