Detailsinfo

A vulnerability classified as critical was found in JoomUnited WP File Download Plugin up to 6.3.4. Affected by this vulnerability is the function delete of the component File Deletion. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. 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. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

The WP File Download plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete function in all versions. This makes it possible for authenticated attackers, with subscriber-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). The two-stage exploit requires a first request to the file.save task to persist the path-traversal string into file metadata, followed by a second request to the file.delete task to trigger the unlink call — both endpoints lack capability checks and nonce enforcement.
