Descriptions

An issue was discovered in the XCloner Backup and Restore plugin before 4.2.13 for WordPress. It gave authenticated attackers the ability to modify arbitrary files, including PHP files. Doing so would allow an attacker to achieve remote code execution. The xcloner_restore.php write_file_action could overwrite wp-config.php, for example. Alternatively, an attacker could create an exploit chain to obtain a database dump.

Se detectó un problema en el plugin XCloner Backup and Restore versiones anteriores a 4.2.13 para WordPress. Otorgaba a atacantes autenticados la capacidad de modificar archivos arbitrarios, incluyendo archivos PHP. Hacerlo permitiría a un atacante lograr una ejecución de código remota. La función write_file_action del archivo xcloner_restore.php podría sobrescribir wp-config.php, por ejemplo. Alternativamente, un atacante podría crear una cadena de explotaciones para obtener un volcado de base de datos.
