CVE-2020-5222 Information

Description

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
