CVE-2020-5222 (GCVE-0-2020-5222)

Vulnerability from cvelistv5 – Published: 2020-01-30 20:50 – Updated: 2024-08-04 08:22

Title

Hard-Coded Key Used For Remember-me Token in OpenCast

Summary

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

Severity

6.8 (Medium)
