The Avaya 4602SW IP Phone (Model 4602D02A) with 2.2.2 and earlier SIP firmware does not use the cnonce parameter in the Authorization header of SIP requests during MD5 digest authentication, which allows remote attackers to conduct man-in-the-middle attacks and hijack or intercept communications.

Security readout for executives and security teams

This issue affects Avaya 4602SW IP Phone Model 4602D02A running SIP firmware 2.2.2 or earlier. During SIP MD5 authentication, the phone omits a client nonce value, weakening protection against interception. In practical terms, legacy desk-phone traffic could be hijacked or listened to if an attacker can position themselves between systems. Exposure is most likely in organizations still running legacy Avaya 4602SW 4602D02A phones with SIP firmware 2.2.2 or earlier. Risk is higher where SIP signaling crosses shared, untrusted, or poorly segmented networks. Prioritize if legacy Avaya SIP phones remain in service, especially in environments handling sensitive calls. The business risk is call interception or hijacking, but urgency is tempered by incomplete exploit and patch evidence in the provided sources. Mitigation focus: Inventory Avaya 4602SW 4602D02A phones and SIP firmware versions.; Review Avaya ASA-2007-263 and current vendor guidance for remediation.; Segment VoIP networks from untrusted user and guest networks..
