CyberRota Analysis
AI-GeneratedThe default security configuration in Opencast versions prior to 19.7 and 20.2 allows an unauthenticated attacker to exploit the JSESSIONID parameter, enabling them to hijack a victim's authenticated session after the victim logs in. This vulnerability can lead to unauthorized access to sensitive data and potentially full administrative account takeover if the victim has administrative privileges. Organizations using affected versions should prioritize upgrading to the fixed versions to mitigate this high-severity risk.

Original NVD Description
Opencast is a free, open-source platform to support the management of educational audio and video content. Prior to versions 19.7 and 20.2, the default security configuration in etc/security/mh_default_org.xml accepts a client-selected JSESSIONID from the ;jsessionid= URL path parameter and does not replace it when the victim logs in. An unauthenticated attacker can send a crafted link to a victim whose browser has no active Opencast session cookie, wait for the victim to authenticate, and then reuse the known identifier as the victim's authenticated session. This can expose the victim's data and actions and can produce full administrative account takeover when the victim is an administrator. This issue is fixed in versions 19.7 and 20.2.
