CVE-2022-25812

El plugin Transposh WordPress Translation de WordPress versiones anteriores a 1.0.8, no comprueba su configuración de depuración, lo que podría permitir a usuarios con altos privilegios, como el administrador, llevar a cabo un RCE.

The Transposh WordPress Translation plugin for WordPress is vulnerable to remote code execution in versions up to, and including, 1.0.8.1. This is due to insufficient extension validation on the log file that can be created via the plugin. This makes it possible for authenticated attackers with administrative level permissions and above to set the log file extension to .php and then update a setting to log PHP executable code to that file which can be used to achieve remote code execution.

Transposh WordPress Translation versions 1.0.8.1 and below have a "save_transposh" action available at "/wp-admin/admin.php?page=tp_advanced" that does not properly validate the "Log file name" allowing an attacker with the "Administrator" role to specify a .php file as the log destination. Since the log file is stored directly within the "/wp-admin" directory, executing arbitrary PHP code is possible by simply sending a crafted request that gets logged.
