CVE-2022-23501

TYPO3 is an open source PHP based web content management system. In versions prior to 8.7.49, 9.5.38, 10.4.33, 11.5.20, and 12.1.1 TYPO3 is vulnerable to Improper Authentication. Restricting frontend login to specific users, organized in different storage folders (partitions), can be bypassed. A potential attacker might use this ambiguity in usernames to get access to a different account - however, credentials must be known to the adversary. This issue is patched in versions 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1.

TYPO3 es un sistema de gestión de contenidos web basado en PHP de código abierto. En versiones anteriores a 8.7.49, 9.5.38, 10.4.33, 11.5.20 y 12.1.1, TYPO3 es vulnerable a una autenticación incorrecta. Se puede omitir la restricción del inicio de sesión en la interfaz a usuarios específicos, organizados en diferentes carpetas de almacenamiento (particiones). Un atacante potencial podría utilizar esta ambigüedad en los nombres de usuario para obtener acceso a una cuenta diferente; sin embargo, el adversario debe conocer las credenciales. Este problema se solucionó en las versiones 8.7.49 ELTS, 9.5.38 ELTS, 10.4.33, 11.5.20, 12.1.1.
