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.","publishedAt":"2024-11-15T15:35:42.433Z","updatedAt":"2024-11-15T21:07:11.500Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Analog Telephone Adaptor (ATA) Software"],"affected":[{"vendor":"Cisco","product":"Cisco Analog Telephone Adaptor (ATA) Software","defaultStatus":"unknown","versions":[{"version":"2.16(1)","status":"affected"},{"version":"2.16(2)","status":"affected"},{"version":"2.1(6)","status":"affected"},{"version":"2.14","status":"affected"},{"version":"3.2(0)","status":"affected"},{"version":"1.1(4)","status":"affected"},{"version":"2.1(5)","status":"affected"},{"version":"3.2(1)","status":"affected"},{"version":"2.15","status":"affected"},{"version":"1.0(0)","status":"affected"},{"version":"1.34","status":"affected"},{"version":"3.1(1)","status":"affected"},{"version":"3.2(4)","status":"affected"},{"version":"3.0(0)","status":"affected"},{"version":"3.2(3)","status":"affected"},{"version":"3.1(0)","status":"affected"},{"version":"3.1(2)","status":"affected"},{"version":"1.2.1","status":"affected"},{"version":"1.2.2","status":"affected"},{"version":"1.2.2 SR1","status":"affected"},{"version":"1.1.2","status":"affected"},{"version":"1.1.0","status":"affected"},{"version":"1.1.1","status":"affected"},{"version":"9.0(3)","status":"affected"},{"version":"9.2(3)","status":"affected"},{"version":"9.2(1)","status":"affected"},{"version":"12.0.1 SR2","status":"affected"},{"version":"11.1.0","status":"affected"},{"version":"12.0.1 SR1","status":"affected"},{"version":"11.1.0 MSR1","status":"affected"},{"version":"12.0.1","status":"affected"},{"version":"11.1.0 MSR2","status":"affected"},{"version":"11.1.0 MSR3","status":"affected"},{"version":"1.2.2 SR2","status":"affected"},{"version":"11.1.0 MSR4","status":"affected"},{"version":"12.0.1 SR3","status":"affected"},{"version":"11.2.1","status":"affected"},{"version":"12.0.1 SR4","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ata19x-multivuln-GEZYVvs"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T19:49:32.184Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/20xxx/CVE-2022-20766.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-20766","state":"PUBLISHED","datePublished":"2024-11-15T15:35:42.433Z","dateUpdated":"2024-11-15T21:07:11.500Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2021-11-02T13:28:29.102Z"},"containers":{"cna":{"title":"Cisco ATA 190 Series Analog Telephone Adapter firmware Cisco Discovery Protocol Denial of Service Vulnerability","descriptions":[{"lang":"en","value":"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.\r\nThis vulnerability is due to an out-of-bounds read when processing Cisco Discovery Protocol packets.
