CVE-2008-6178: Fckeditor

High severity, CVSS 7.5. EPSS: 7.8% chance of exploitation in the next 30 days.

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. NOTE: some of these details are obtained from third party information.
