An attacker could exploit this vulnerability by ensuring that the device will connect to an SSL/TLS server that is using specific encryption parameters. A successful exploit could allow the attacker to cause the affected device to unexpectedly reload, resulting in a DoS condition.","provenance":"source","from":"CVE.org"},"cvss":{"score":7.7,"severity":"HIGH","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00543,"percentile":0.45502,"provenance":"source"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ssl-client-dos-cCrQPkA","tags":[]}],"priority":{"score":14.5,"factors":[{"name":"EPSS percentile","points":9.1},{"name":"CVSS severity","points":5.39}]},"vendorSlug":"cisco","affectedVersions":[{"vendor":"Cisco","product":"Cisco Adaptive Security Appliance (ASA) Software","versions":["9.14.1","9.14.1.10","9.14.1.15","9.14.1.19","9.14.1.30","9.14.2","9.14.2.4","9.14.2.8","9.14.2.13","9.14.2.15"]},{"vendor":"Cisco","product":"Cisco Firepower Threat Defense Software","versions":["6.6.0","6.6.0.1","6.6.1","6.6.3","6.6.4","6.6.5","6.6.5.1","6.6.5.2","6.7.0","6.7.0.1"]}],"euvd":{"id":"EUVD-2022-26177","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-class-cisco-asa-cwe-120"}}
