Vulnerability Title
FileGator privilege escalation
Source: CVE Program / CVE List V5
Vulnerability Description
FileGator accepts arbitrary Unix permission values via the '/chmoditems' API endpoint and passes the value directly to PHP's native 'chmod()' function through 'octdec()' conversion, with no validation. This allows an authenticated user with 'chmod' permission to upgrade their privileges to root.
