Cisco has disclosed a vulnerability in the web-based management interface of Cisco SPA112 2-Port Phone Adapters, allowing an unauthenticated, remote attacker to execute arbitrary code on the devices.
These phone adapters are a popular choice in the industry for incorporating analog phones into VoIP networks without upgrading.
Since Cisco SPA112 has reached the end of its life, it is no longer supported by the vendor and will not receive a security update.
Cisco has provided no mitigations for CVE-2023-20136.
Cisco's security bulletin aims at raising awareness of the need to replace the impacted phone adapters or implement additional security layers to protect them from attacks.
The recommended replacement model is Cisco ATA 190 Series Analog Telephone Adapter, which has a designated end-of-life date on March 31, 2024.
