Description

The Modula Image Gallery plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the 'ajax_unzip_file' function in versions 2.13.1 to 2.13.2. This makes it possible for authenticated attackers, with Author-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).

• CWE-22Improper 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.
