Descriptions

The Spam protection, Anti-Spam, FireWall by CleanTalk plugin for WordPress is vulnerable to unauthorized Arbitrary Plugin Installation due to an authorization bypass via reverse DNS spoofing on the checkWithoutToken function in all versions up to, and including, 6.43.2. This makes it possible for unauthenticated attackers to install and activate arbitrary plugins which can be leveraged to achieve remote code execution if another vulnerable plugin is installed and activated.

El complemento Spam protection, Anti-Spam, FireWall by CleanTalk para WordPress es vulnerable a la instalación no autorizada de complementos arbitrarios debido a una omisión de autorización mediante suplantación de DNS inversa en la función checkWithoutToken en todas las versiones hasta la 6.43.2 incluida. Esto permite que atacantes no autenticados instalen y activen complementos arbitrarios que pueden aprovecharse para lograr la ejecución remota de código si se instala y activa otro complemento vulnerable.
