The Htek UC902 VoIP phone web management interface contains several buffer overflow vulnerabilities in the firmware version 2.0.4.4.46, which allow an attacker to crash the device (DoS) without authentication or execute code (authenticated as a user) to spawn a remote shell as a root user.
The product writes data past the end, or before the beginning, of the intended buffer.
