Descriptions

Opencast before 7.6 and 8.1 enables a remember-me cookie based on a hash created from the username, password, and an additional system key. This means that an attacker getting access to a remember-me token for one server can get access to all servers which allow log-in using the same credentials without ever needing the credentials. This problem is fixed in Opencast 7.6 and Opencast 8.1

Opencast versiones anteriores a 7.6 y 8.1, habilita una cookie remember-me basada en un hash creado a partir del nombre de usuario, contraseña y una clave de sistema adicional. Esto significa que un atacante que obtiene acceso a un token remember-me para un servidor puede obtener acceso a todos los servidores que permiten el inicio de sesión con las mismas credenciales sin necesidad alguna de las credenciales. Este problema se corrigió en Opencast versión 7.6 y Opencast versión 8.1.
