Remote code execution via nonce-free ZIP extraction
Published Dec 21, 2021 · Updated Aug 3, 2024
Cross-site request forgery in wpWax Directorist before 7.0.6.2 allows remote attackers to upload executable PHP archives. The atbdp_download_file AJAX action accepts an attacker-controlled download_item[download_link], retrieves the ZIP, and extracts its contents under wp-content/plugins without a CSRF nonce check. An authenticated WordPress user must submit the forged form; successful exploitation installs a PHP shell that permits arbitrary server-side code execution.
