{"id":"CVE-2022-20715","state":"PUBLISHED","title":"Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Remote Access SSL VPN Denial of Service Vulnerability","description":"A vulnerability in the remote access SSL VPN features of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper validation of errors that are logged as a result of client connections that are made using remote access VPN. An attacker could exploit this vulnerability by sending crafted requests to an affected system. A successful exploit could allow the attacker to cause the affected device to restart, resulting in a DoS condition.","publishedAt":"2022-05-03T03:16:28.466Z","updatedAt":"2024-09-16T17:19:10.789Z","severity":{"score":8.6,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","source":"cisco"},"assigner":"cisco","products":["Cisco Cisco Adaptive Security Appliance (ASA) Software"],"affected":[{"vendor":"Cisco","product":"Cisco Adaptive Security Appliance (ASA) Software","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-dos-tL4uA4AA"],"weaknesses":["CWE-399"],"ingestedAt":"2026-10-29T19:49:32.184Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/20xxx/CVE-2022-20715.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-20715","state":"PUBLISHED","datePublished":"2022-05-03T03:16:28.466Z","dateUpdated":"2024-09-16T17:19:10.789Z","assignerShortName":"cisco","assignerOrgId":"d1c1063e-7a18-46af-9102-31f8928bc633","dateReserved":"2021-11-02T00:00:00.000Z"},"containers":{"cna":{"title":"Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Remote Access SSL VPN Denial of Service Vulnerability","descriptions":[{"lang":"en","value":"A vulnerability in the remote access SSL VPN features of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
