MW WP Form <= 5.0.3 - Improper Limitation of File Name to Unauthenticated Arbitrary File Deletion
Strategic Overview
Vulnerability Overview
The MW WP Form plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 5.0.3. This is due to the plugin not properly validating the path of an uploaded file prior to deleting it. This makes it possible for unauthenticated attackers to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution possible.
Technical Analysis
REMEDIATION: Update to version 5.0.4, 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.
