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.

Weakness

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.
