AI-suggested

1. Upgrade Open OnDemand installations to versions 3.1.15 or 4.0.7 (or later) immediately to ensure proper password rotation is enforced regardless of TurboVNC version. 2. If upgrading OOD is not immediately feasible, downgrade TurboVNC to versions below 3.1.2 as a temporary workaround to prevent password reuse. 3. Enforce strict access controls and monitoring on the OOD portal to detect unusual session sharing or multiple logins from the same session link. 4. Educate users on the risks of sharing active session links and implement policies to minimize link sharing. 5. Implement multi-factor authentication (MFA) on the OOD portal to reduce the risk of unauthorized authentication. 6. Regularly audit session logs and monitor for anomalous activities indicative of session hijacking. 7. Consider network segmentation and VPN usage to restrict access to the OOD portal to trusted networks and users. 8. Coordinate with HPC administrators to review and harden the overall security posture of the HPC environment, including VNC session management and password policies.

Description

Open OnDemand is an open-source HPC portal. Prior to versions 3.1.15 and 4.0.7, noVNC interactive applications did not correctly rotate the password when TurboVNC was higher than version 3.1.2. The likelihood of exploitation is low as a user would need to share their link to an active desktop session and the other user would need to be authenticated to the portal. But obtaining the link would allow that user to perform any actions as the original user and access their data. Open OnDemand 3.1.15 and 4.0.7 have patched this vulnerability and correctly rotate passwords for any version of TurboVNC. As a workaround, downgrade TurboVNC to a version lower than 3.1.2.
