Vulnerability Overview

The Snow Monkey Forms plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'generate_user_dirpath' function in all versions up to, and including, 12.0.3. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

Technical Analysis

REMEDIATION: Update to version 12.0.4, 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.
