CVE-2022-20660 – Cisco IP Phones Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2022-20660
A vulnerability in the information storage architecture of several Cisco IP Phone models could allow an unauthenticated, physical attacker to obtain confidential information from an affected device. This vulnerability is due to unencrypted storage of confidential information on an affected device. An attacker could exploit this vulnerability by physically extracting and accessing one of the flash memory chips. A successful exploit could allow the attacker to obtain confidential information from the device, which could be used for subsequent attacks.

CVE-2020-3111 – Cisco IP Phone Remote Code Execution and Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2020-3111
A vulnerability in the Cisco Discovery Protocol implementation for the Cisco IP Phone could allow an unauthenticated, adjacent attacker to remotely execute code with root privileges or cause a reload of an affected IP phone. 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. • http://packetstormsecurity.com/files/156203/Cisco-Discovery-Protocol-CDP-Remote-Device-Takeover.html https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20200205-voip-phones-rce-dos • CWE-20: Improper Input Validation •
