Myriad <= 2.0 - Arbitrary File Deletion
Strategic Overview
Vulnerability Overview
The Myriad Theme for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.1. This is due to the '_mysite_delete_skin_zip' parameter in the 'dl-skin.php' file. This makes it possible for unauthenticated attackers to delete any file on the server of the vulnerable service.
Technical Analysis
REMEDIATION: Update to version 2.1, 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.
