| Description | The Post Export Import with Media plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.13.1 via the import_media_file_secure function. This is due to insufficient file extension validation caused by a trailing-dot filename bypass, where the extension allow-list check in ajax_import_media_start() uses pathinfo() on the raw ZIP entry name (e.g., 'shell.php.'), which returns an empty string for the extension, causing the allow-list guard to be skipped and the file to be extracted to a temporary location, after which import_media_file_secure() copies it into the WordPress uploads directory without re-validating the extension. This makes it possible for authenticated attackers, with administrator-level access and above, to upload files that may be executable, which makes remote code execution possible. | |
