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.","state":"PUBLIC","assigner":"psirt@cisco.com","published_at":"2023-03-03 16:15:00","updated_at":"2023-11-07 04:06:00"},"problem_types":["NVD-CWE-noinfo"],"metrics":[],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-finesse-proxy-dos-vY5dQhrV","name":"20230301 Cisco Finesse Reverse Proxy VPN-less Access to Finesse Desktop Denial of Service Vulnerability","refsource":"CISCO","tags":[],"title":"Cisco Finesse Reverse Proxy VPN-less Access to Finesse Desktop Denial of Service Vulnerability","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.cve.org/CVERecord?id=CVE-2023-20088","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2023-20088","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2023","cve_id":"20088","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"finesse","cpe6":"*","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2023","cve_id":"20088","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"finesse","cpe6":"12.6\\(1\\)","cpe7":"-","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2023","cve_id":"20088","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"finesse","cpe6":"12.6\\(1\\)","cpe7":"es01","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2023","cve_id":"20088","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"finesse","cpe6":"12.6\\(1\\)","cpe7":"es02","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"},{"cve_year":"2023","cve_id":"20088","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"cisco","cpe5":"finesse","cpe6":"12.6\\(1\\)","cpe7":"es03","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"psirt@cisco.com","DATE_PUBLIC":"2023-03-01T16:00:00","ID":"CVE-2023-20088","STATE":"PUBLIC","TITLE":"Cisco Finesse Reverse Proxy VPN-less Access to Finesse Desktop Denial of Service Vulnerability"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"Cisco Unified Contact Center Enterprise ","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"Cisco"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","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.
