The hiWeb Export Posts plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 0.9.0.0. This is due to missing or incorrect nonce validation on the tool-dashboard-history.php file. This makes it possible for unauthenticated attackers 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), via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
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.
