Vulnerability Overview

The WPFunnels plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the wpfnl_delete_log() function in all versions up to, and including, 3.6.2. This makes it possible for authenticated attackers, with Administrator-level access and above, 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 3.6.3, 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.
