This vulnerability is due to insufficient validation of the login URL. An attacker could exploit this vulnerability by persuading a user to access a site that is under the control of the attacker, allowing the attacker to modify the login URL. A successful exploit could allow the attacker to intercept a successful SAML assertion and use that assertion to establish a remote access VPN session toward the affected device with the identity and permissions of the hijacked user, resulting in access to the protected network."}],"affected":[{"vendor":"Cisco","product":"Cisco Adaptive Security Appliance (ASA) Software","versions":[{"version":"9.18.1","status":"affected"},{"version":"9.18.1.3","status":"affected"},{"version":"9.18.2","status":"affected"},{"version":"9.18.2.5","status":"affected"},{"version":"9.18.2.7","status":"affected"},{"version":"9.18.2.8","status":"affected"},{"version":"9.18.3","status":"affected"},{"version":"9.18.3.39","status":"affected"},{"version":"9.18.3.46","status":"affected"},{"version":"9.19.1.5","status":"affected"},{"version":"9.19.1.9","status":"affected"},{"version":"9.19.1.12","status":"affected"}]},{"vendor":"Cisco","product":"Cisco Firepower Threat Defense Software","versions":[{"version":"7.2.4","status":"affected"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"URL Redirection to Untrusted Site ('Open Redirect')","type":"cwe","cweId":"CWE-601"}]}],"references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-saml-hijack-ttuQfyz","name":"cisco-sa-asaftd-saml-hijack-ttuQfyz"}],"metrics":[{"format":"cvssV3_1","cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"CHANGED","confidentialityImpact":"LOW","integrityImpact":"LOW","availabilityImpact":"NONE"}}],"exploits":[{"lang":"en","value":"The Cisco Product Security Incident Response Team (PSIRT) is not aware of any public announcements or malicious use of the vulnerability that is described in this advisory."}],"source":{"advisory":"cisco-sa-asaftd-saml-hijack-ttuQfyz","discovery":"EXTERNAL","defects":["CSCwf85757"]}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T09:05:36.229Z"},"title":"CVE Program Container","references":[{"url":"https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asaftd-saml-hijack-ttuQfyz","name":"cisco-sa-asaftd-saml-hijack-ttuQfyz","tags":["x_transferred"]}]}]}}
