CVE-2022-20687 Detail

Current Description

Multiple vulnerabilities in the Link Layer Discovery Protocol (LLDP) functionality of Cisco ATA 190 Series Analog Telephone Adapter firmware could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device and cause the LLDP service to restart. These vulnerabilities are due to missing length validation of certain LLDP packet header fields. An attacker could exploit these vulnerabilities by sending a malicious LLDP packet to an affected device. A successful exploit could allow the attacker to execute code on the affected device and cause LLDP to restart unexpectedly, resulting in a denial of service (DoS) condition.
