Descriptions

TYPO3 is an open source PHP based web content management system. In TYPO3 before versions 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1 user session identifiers were stored in cleartext - without processing of additional cryptographic hashing algorithms. This vulnerability cannot be exploited directly and occurs in combination with a chained attack - like for instance SQL injection in any other component of the system. This is fixed in versions 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1.

En TYPO3 versiones anteriores 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1 los identificadores de sesión de usuario se almacenaban en texto claro - sin procesar algoritmos de hash criptográficos adicionales. Esta vulnerabilidad no puede ser explotada directamente y ocurre en combinación con un ataque encadenado - como por ejemplo la inyección SQL en cualquier otro componente del sistema. Esto se ha corregido en las versiones 6.2.57, 7.6.51, 8.7.40, 9.5.25, 10.4.14, 11.1.1
