CVE-2022-20766 (GCVE-0-2022-20766)
Vulnerability from cvelistv5 – Published: 2024-11-15 15:35 – Updated: 2024-11-15 21:07
VLAI?
Summary
A vulnerability in the Cisco Discovery Protocol functionality of Cisco ATA 190 Series Adaptive Telephone Adapter firmware could allow an unauthenticated, remote attacker to cause a DoS condition on an affected device.
This vulnerability is due to an out-of-bounds read when processing Cisco Discovery Protocol packets. An attacker could exploit this vulnerability by sending crafted Cisco Discovery Protocol packets to an affected device. A successful exploit could allow the attacker to cause a service restart.Cisco has released firmware updates that address this vulnerability. There are no workarounds that address this vulnerability.
