A denial of service (DoS) vulnerability and remote code execution (RCE) exists in Cisco IP Phones due to missing checks when processing Cisco Discovery Protocol messages. An unauthenticated attacker can exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition.
