The Sencore SMP100 SMP Media Platform (firmware versions V4.2.160, V60.1.4, V60.1.29) is vulnerable to session hijacking due to improper session management on the /UserManagement.html endpoint. Attackers who are on the same network as the victim and have access to the targets logged-in session can access the endpoint and add new users without any authentication. This allows attackers to gain unauthorized access to the system and perform malicious activities.
According to WASC, “Insufficient Session Expiration is when a web site permits an attacker to reuse old session credentials or session IDs for authorization.”
