Mitel 6940 Firmware

The Web UI component of Mitel MiVoice 6800 and 6900 series SIP Phones with firmware before 5.1.0.SP5 could allow an unauthenticated attacker to expose sensitive information due to improper memory handling during failed login attempts.

A key length vulnerability in the implementation of the SRTP 128-bit key on Mitel 6800 and 6900 SIP series phones, versions 5.1.0.2051 SP2 and earlier, could allow an attacker to launch a man-in-the-middle attack when SRTP is used in a call. A successful exploit may allow the attacker to intercept sensitive information.
