CyberRota Analysis
AI-GeneratedAn authenticated TURN user in Coturn version 4.15.0 can exploit a flaw related to session management when the server's mobility feature is enabled, allowing them to create an unbounded number of server-side sessions. This can lead to memory exhaustion on the server, potentially impacting its availability. Organizations using Coturn should prioritize upgrading to version 4.16.0 to mitigate this vulnerability.

Original NVD Description
Coturn is a free open source implementation of TURN and STUN Server. In 4.15.0, an authenticated TURN user can repeatedly resume one allocation from fresh UDP 5-tuples without completing a handoff when the server enables --mobility. mobile_begin_transition() in src/server/ns_turn_server.c disarms each new session's allocation timeout and overwrites the allocation's single mobile_pending_resume link, leaving earlier pending sessions unreachable by the cleanup path, while copy_auth_parameters() ignores inc_quota() failure. The attacker can therefore retain unbounded server-side sessions and exhaust process memory even when --user-quota=1 is configured. This issue is fixed in version 4.16.0.
