{"id":"CVE-2022-20814","state":"PUBLISHED","title":"Cisco Expressway Series and Cisco TelePresence VCS Improper Certificate Validation Vulnerability","description":"A vulnerability in the certificate validation of Cisco&nbsp;Expressway-C and Cisco&nbsp;TelePresence VCS could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data.&nbsp;&nbsp;The vulnerability is due to a lack of validation of the SSL server certificate that an affected device receives when it establishes a connection to a Cisco&nbsp;Unified Communications Manager device. An attacker could exploit this vulnerability by using a man-in-the-middle technique to intercept the traffic between the devices, and then using a self-signed certificate to impersonate the endpoint. A successful exploit could allow the attacker to view the intercepted traffic in clear text or alter the contents of the traffic.\r\nNote: Cisco&nbsp;Expressway-E is not affected by this vulnerability.Cisco&nbsp;has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.","publishedAt":"2024-11-15T15:32:47.058Z","updatedAt":"2024-11-15T21:15:35.408Z","severity":{"score":7.4,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco TelePresence Video Communication Server (VCS) Expressway"],"affected":[{"vendor":"Cisco","product":"Cisco TelePresence Video Communication Server (VCS) Expressway","defaultStatus":"unknown","versions":[{"version":"X8.11.2","status":"affected"},{"version":"X8.6","status":"affected"},{"version":"X8.11.3","status":"affected"},{"version":"X8.2.2","status":"affected"},{"version":"X8.8.3","status":"affected"},{"version":"X8.11.0","status":"affected"},{"version":"X12.5.2","status":"affected"},{"version":"X8.1.1","status":"affected"},{"version":"X8.9","status":"affected"},{"version":"X12.5.1","status":"affected"},{"version":"X12.5.6","status":"affected"},{"version":"X8.7.3","status":"affected"},{"version":"X12.6.0","status":"affected"},{"version":"X8.11.1","status":"affected"},{"version":"X8.5","status":"affected"},{"version":"X8.9.1","status":"affected"},{"version":"X8.10.2","status":"affected"},{"version":"X8.8.2","status":"affected"},{"version":"X8.5.3","status":"affected"},{"version":"X8.1","status":"affected"},{"version":"X8.9.2","status":"affected"},{"version":"X8.11.4","status":"affected"},{"version":"X12.5.4","status":"affected"},{"version":"X8.8.1","status":"affected"},{"version":"X8.2.1","status":"affected"},{"version":"X8.5.1","status":"affected"},{"version":"X8.6.1","status":"affected"},{"version":"X8.1.2","status":"affected"},{"version":"X8.8","status":"affected"},{"version":"X8.10.0","status":"affected"},{"version":"X12.5.3","status":"affected"},{"version":"X8.10.1","status":"affected"},{"version":"X12.5.7","status":"affected"},{"version":"X8.10.3","status":"affected"},{"version":"X8.7.1","status":"affected"},{"version":"X8.2","status":"affected"},{"version":"X12.5.8","status":"affected"},{"version":"X8.7","status":"affected"},{"version":"X8.5.2","status":"affected"},{"version":"X12.5.9","status":"affected"},{"version":"X12.5.0","status":"affected"},{"version":"X8.10.4","status":"affected"},{"version":"X8.7.2","status":"affected"},{"version":"X12.5.5","status":"affected"},{"version":"X12.6.1","status":"affected"},{"version":"X12.6.2","status":"affected"},{"version":"X12.6.3","status":"affected"},{"version":"X12.6.4","status":"affected"},{"version":"X12.7.0","status":"affected"},{"version":"X12.7.1","status":"affected"},{"version":"X14.0.0","status":"affected"},{"version":"X14.0.1","status":"affected"},{"version":"X14.0.2","status":"affected"},{"version":"X14.0.3","status":"affected"},{"version":"X14.0.4","status":"affected"},{"version":"X14.0.5","status":"affected"},{"version":"X14.0.6","status":"affected"},{"version":"X14.0.7","status":"affected"},{"version":"X14.0.8","status":"affected"},{"version":"X14.0.9","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-expressway-csrf-sqpsSfY6","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxr-bng-Gmg5Gxt","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ncs4k-tl1-GNnLwC6","https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-xr-cdp-wnALzvT2"],"weaknesses":["CWE-295"],"ingestedAt":"2026-10-29T19:49:32.184Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/20xxx/CVE-2022-20814.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-20814","state":"PUBLISHED","datePublished":"2024-11-15T15:32:47.058Z","dateUpdated":"2024-11-15T21:15:35.408Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2021-11-02T13:28:29.175Z"},"containers":{"cna":{"title":"Cisco Expressway Series and Cisco TelePresence VCS Improper Certificate Validation Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the certificate validation of Cisco&nbsp;Expressway-C and Cisco&nbsp;TelePresence VCS could allow an unauthenticated, remote attacker to gain unauthorized access to sensitive data.&nbsp;&nbsp;The vulnerability is due to a lack of validation of the SSL server certificate that an affected device receives when it establishes a connection to a Cisco&nbsp;Unified Communications Manager device.
