Summary

FileGator accepts arbitrary Unix permission values via the '/chmoditems' API endpoint and passes them directly to PHP's 'chmod()' function via 'octdec()' conversion without validation. An authenticated user with 'chmod' permission can escalate privileges to root.

Risk Assessment

An attacker can gain full control of the FileGator server, compromising confidentiality, integrity, and availability of data.

Recommendation

Update FileGator to a version that validates permission values. Restrict 'chmod' permission to trusted users only.
