A vulnerability in the Mitel 6800 Series, 6900 Series, and 6900w Series SIP Phones, including the 6970 Conference Unit through 6.4 SP4, could allow an unauthenticated attacker to perform a file upload attack due to missing authentication mechanisms. A successful exploit could allow an attacker to upload arbitrary WAV files, which may potentially exhaust the phone's storage without affecting the phone's availability or operation.
