FCKeditor arbitrary file upload

Description

Multiple vendor applications utilize FCKeditor. FCKeditor contains functionality to handle file uploads and file management. A remote attacker could use this functionality to upload malicious executable files on the system. To test file upload capabilities, Acunetix WVS created a file named Acunetix_WVS_File_Upload_test.txt on the server.

Remediation

It is recommended to disable the file upload functionality in FCKeditor (if not required).
