Cudy TR3000 before 2.5.42 contains an unauthenticated stack buffer overflow vulnerability in the stun_client TR-111 UDP Connection Request parser that parses requests before verifying username or HMAC. Remote attackers can send a single crafted UDP datagram lacking a space in the request line, causing strncpy() to overflow a 10-byte stack buffer and crash stun_client for denial of service.
