Official Description

Unrestricted file upload vulnerability in editor/filemanager/browser/default/connectors/php/connector.php in FCKeditor 2.2, as used in Falt4 CMS, Nuke ET, and other products, allows remote attackers to execute arbitrary code by creating a file with PHP sequences preceded by a ZIP header, uploading this file via a FileUpload action with the application/zip content type, and then accessing this file via a direct request to the file in UserFiles/File/, probably a related issue to CVE-2005-4094.

Technical Analysis

CVE-2008-6178 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A proof-of-concept (PoC) exploit exists for CVE-2008-6178. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
