Descriptions

Yii 2 (yiisoft/yii2) before version 2.0.38 is vulnerable to remote code execution if the application calls `unserialize()` on arbitrary user input. This is fixed in version 2.0.38. A possible workaround without upgrading is available in the linked advisory.

Yii 2 (yiisoft/yii2) versiones anteriores a 2.0.38 es vulnerable a una Ejecución de Código Remota si la aplicación llama a "unserialize()" en una entrada arbitraria de usuario. Esto es corregido en la versión 2.0.38. Una posible solución alternativa sin actualización está disponible en el aviso vinculado
