Overview
6800 Series Command Injection
A vulnerability in the Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones through 6.4 SP4 (R6.4.0.4006), and the 6970 Conference Unit through 6.4 SP4 (R6.4.0.4006) or version V1 R0.1.0, could allow an unauthenticated attacker to conduct a command injection attack due to insufficient parameter sanitization.
