Coturn versions prior to 4.15.0 have a vulnerability where an on-path attacker can append attributes after the MESSAGE-INTEGRITY attribute in an authenticated STUN request over plain UDP or TCP. This allows modification of the STUN header length and recomputation of the unkeyed FINGERPRINT while the original HMAC remains valid. As a result, server-side parsing continues past MESSAGE-INTEGRITY, enabling the attacker to override allocation lifetime, inject permissions, or bypass origin checks. Deployments using TLS or DTLS are not affected by this issue. The vulnerability is fixed in Coturn version 4.15.0.
