Descriptions

In TYPO3 installations with the "mediace" extension from version 7.6.2 and before version 7.6.5, it has been discovered that an internal verification mechanism can be used to generate arbitrary checksums. The allows to inject arbitrary data having a valid cryptographic message authentication code and can lead to remote code execution. To successfully exploit this vulnerability, an attacker must have access to at least one `Extbase` plugin or module action in a TYPO3 installation. This is fixed in version 7.6.5 of the "mediace" extension for TYPO3.

En las instalaciones de TYPO3 con la extensión "mediace" desde la versión 7.6.2 y anteriores a la versión 7.6.5, se ha detectado que se puede utilizar un mecanismo de verificación interna para generar sumas de comprobación arbitrarias. Permite inyectar datos arbitrarios que tienen un código de autenticación de mensaje criptográfico válido y puede conllevar a una ejecución de código remota. Para explotar con éxito esta vulnerabilidad, un atacante debe tener acceso al menos a un plugin "Extbase" o acción de módulo en una instalación TYPO3. Esto se corrigió en la versión 7.6.5 de la extensión "mediace" para TYPO3
