Vulnerability Overview

The mTheme-Unus theme for WordPress is vulnerable to Directory Traversal in versions up to 2.3 via the 'files' parameter found in the css/css.php file. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.

Technical Analysis

REMEDIATION: Update to version 2.3, 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.
