The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could 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. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).","2020-02-05",8.8,"v3.1","High",false,0.03095,{"cveId":26,"description":27,"publishedDate":28,"cvssScore":29,"cvssVersion":21,"severity":30,"isKev":23,"epssScore":31},"CVE-2019-16008","A vulnerability in the web-based GUI of Cisco IP Phone 6800, 7800, and 8800 Series with Multiplatform Firmware could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the web-based interface of an affected system.
