Summary

Nexterm through 1.2.2-BETA contains a missing authorization vulnerability that allows authenticated users to hibernate, resume, or terminate other users' remote sessions via session lifecycle routes. Attackers who obtain a session ID can call the hibernate, resume, or DELETE connection endpoints to disrupt live SSH, RDP, VNC, or SFTP sessions.

Risk Assessment

Organizations using Nexterm are exposed to insider or compromised-account attacks that can disrupt critical remote administrative sessions, causing downtime and potential data loss. The lack of session-level authorization may also allow an attacker to intentionally interfere with other users' work.

Recommendation

Update Nexterm to a version later than 1.2.2-BETA as soon as possible if available, or implement access controls on session lifecycle routes. Additionally, monitor and restrict access to session IDs and verify that users have appropriate permissions to manage other users' sessions.
