Vulnerability Overview

The Awesome Support – WordPress HelpDesk & Support Plugin plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 6.1.4. This is due to insufficient controls on paths being supplied when a user deletes an attachment from a ticket. This makes it possible for authenticated attackers, with ticket submitting-level access to delete arbitrary files on the site which can be used to achieve remote code execution and take over the site.

Technical Analysis

REMEDIATION: Update to version 6.1.5, or a newer patched version --- IDENTIFIER: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')) The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
