What is CVE-2022-20688?

A flaw in the Cisco Discovery Protocol functionality of the Cisco ATA 190 Series Analog Telephone Adapter firmware allows unauthenticated remote attackers to send specially crafted packets that lack proper length validation. This can lead to arbitrary code execution on the affected device, causing unexpected service restarts and potential denial-of-service conditions. Successful exploitation may compromise the integrity and availability of the device, highlighting the importance of timely updates to mitigate this risk.
