Cisco has addressed a critical security vulnerability found in the Web UI of multiple IP Phone models that unauthenticated and remote attackers can exploit in remote code execution attacks.
The security vulnerabilities were discovered by Zack Sanchez of the Cisco Advanced Security Initiatives Group during internal security testing.
While Cisco released security updates to address the CVE-2023-20078 RCE vulnerability, the company said it would not release patches to fix the CVE-2023-20079 DoS flaw.
"Cisco Unified IP Phone 7900 Series and Cisco Unified IP Conference Phone 8831 have entered the end-of-life process," the company explained.
Cisco also announced in December that it would release patches for a high-severity zero-day vulnerability with public exploit code found in the Cisco Discovery Protocol processing feature of Cisco IP Phones running 7800 and 8800 Series firmware.
In February 2020, Cisco patched five other RCE and DoS vulnerabilities in the Cisco Discovery Protocol, collectively known as CDPwn and potentially affecting tens of millions of enterprise devices.
