Title: TYPO3 CMS de TYPO3, Description: El frontend de caché de TYPO3 (VariableFrontend) y el almacén persistente de clave-valor (Registry) deserializaban cargas útiles PHP sin validación de integridad ni restricciones de clase. Un atacante con acceso de escritura al backend de almacenamiento subyacente (almacén de caché o tabla de base de datos sys_registry) podría inyectar una carga útil serializada manipulada para desencadenar una inyección de objetos PHP, explotando potencialmente una cadena de gadgets para lograr la ejecución remota de código u otros efectos de alto impacto. Explotar esta vulnerabilidad requiere acceso de escritura local directo al almacenamiento, como la base de datos SQL o el sistema de archivos. Este problema afecta a las versiones de TYPO3 CMS anteriores a 10.4.57, 11.0.0-11.5.51, 12.0.0-12.4.46, 13.0.0-13.4.31 y 14.0.0-14.3.3.

TYPO3's cache frontend (VariableFrontend) and persistent key-value store (Registry) deserialized PHP payloads without integrity validation or class restrictions. An attacker with write access to the underlying storage backend (cache store or sys_registry database table) could inject a crafted serialized payload to trigger PHP Object Injection, potentially exploiting a gadget chain to achieve Remote Code Execution or other high-impact effects. Exploiting this vulnerability requires direct local write access to the storage, such as the SQL database or file system. This issue affects TYPO3 CMS versions before 10.4.57, 11.0.0-11.5.51, 12.0.0-12.4.46, 13.0.0-13.4.31 and 14.0.0-14.3.3.
