Zombify <= 1.7.5 - Authenticated (Subscriber+) Path Traversal to Arbitrary File Read
Strategic Overview
Vulnerability Overview
The Zombify plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.7.5. This is due to insufficient input validation in the zf_get_file_by_url function. This makes it possible for authenticated attackers, with subscriber-level access and above, to read arbitrary files on the server, including sensitive system files like /etc/passwd, via a forged request. It's worth noting that successfully exploiting this vulnerability relies on a race condition as the file generated will be deleted immediately.
Technical Analysis
REMEDIATION: Update to version 1.7.6, 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.
