{"id":"CVE-2023-20088","state":"PUBLISHED","title":"Cisco Finesse Reverse Proxy VPN-less Access to Finesse Desktop Denial of Service Vulnerability","description":"A vulnerability in the nginx configurations that are provided as part of the VPN-less reverse proxy for Cisco Finesse could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition for new and existing users who are connected through a load balancer. This vulnerability is due to improper IP address filtering by the reverse proxy. An attacker could exploit this vulnerability by sending a series of unauthenticated requests to the reverse proxy. A successful exploit could allow the attacker to cause all current traffic and subsequent requests to the reverse proxy through a load balancer to be dropped, resulting in a DoS condition.","publishedAt":"2023-03-03T00:00:00.000Z","updatedAt":"2024-10-28T16:33:23.491Z","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 Unified Contact Center Enterprise"],"affected":[{"vendor":"Cisco","product":"Cisco Unified Contact Center Enterprise","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-finesse-proxy-dos-vY5dQhrV"],"weaknesses":["CWE-285"],"ingestedAt":"2026-10-29T20:05:36.141Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/20xxx/CVE-2023-20088.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-20088","state":"PUBLISHED","datePublished":"2023-03-03T00:00:00.000Z","dateUpdated":"2024-10-28T16:33:23.491Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2022-10-27T00:00:00.000Z"},"containers":{"cna":{"title":"Cisco Finesse Reverse Proxy VPN-less Access to Finesse Desktop Denial of Service Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the nginx configurations that are provided as part of the VPN-less reverse proxy for Cisco Finesse could allow an unauthenticated, remote attacker to create a denial of service (DoS) condition for new and existing users who are connected through a load balancer.
