Descriptions

The Import XML and RSS Feeds WordPress plugin before 2.1.5 contains a web shell, allowing unauthenticated attackers to perform RCE. The plugin/vendor was not compromised and the files are the result of running a PoC for a previously reported issue (https://wpscan.com/vulnerability/d4220025-2272-4d5f-9703-4b2ac4a51c42) and not deleting the created files when releasing the new version.

El complemento de WordPress Import XML and RSS Feeds anterior a 2.1.5 contiene un shell web que permite a atacantes no autenticados realizar RCE. El complemento/proveedor no se vio comprometido y los archivos son el resultado de ejecutar una PoC para un problema informado anteriormente (https://wpscan.com/vulnerability/d4220025-2272-4d5f-9703-4b2ac4a51c42) y no eliminar los archivos creados cuando lanzando la nueva versión.

The Import XML and RSS Feeds for WordPress is vulnerable to remote code execution in versions up to, and including, 2.1.4. This is due to the plugin vendor leaving a malicious file behind when patching CVE-2023-4300. This makes it possible for unauthenticated attackers to access the 169227090864de013cac47b.php file and achieve remote code execution.
