Summary

The vulnerability in Cisco IP Phone 7940 and 7960 allows remote attackers to execute a denial of service attack, specifically causing a device reboot. This can be achieved through a specific manipulation of SIP (Session Initiation Protocol) messages. By sending a sequence of ten invalid SIP INVITE and OPTIONS messages, or an invalid SIP INVITE message containing a remote tag followed by two particular SIP OPTIONS messages, an attacker can disrupt the normal operation of these devices. This poses significant implications for businesses relying on these communication tools.
