The client update process is executed after a successful VPN connection is established.\r\n\r This vulnerability exists because improper permissions are assigned to a temporary directory that is created during the update process. An attacker could exploit this vulnerability by abusing a specific function of the Windows installer process. A successful exploit could allow the attacker to execute code with SYSTEM privileges." } ], "metrics": { "cvssMetricV31": [ { "source": "nvd@nist.gov", "type": "Primary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 7.8, "baseSeverity": "HIGH" }, "exploitabilityScore": 1.8, "impactScore": 5.9 }, { "source": "ykramarz@cisco.com", "type": "Secondary", "cvssData": { "version": "3.1", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "baseScore": 7.8, "baseSeverity": "HIGH" }, "exploitabilityScore": 1.8, "impactScore": 5.9 } ] }, "weaknesses": [ { "source": "nvd@nist.gov", "type": "Primary", "description": [ { "lang": "en", "value": "CWE-276" } ] } ], "configurations": [ { "nodes": [ { "operator": "OR", "negate": false, "cpeMatch": [ { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:anyconnect_secure_mobility_client:*:*:*:*:*:windows:*:*", "versionEndExcluding": "4.10.07061", "matchCriteriaId": "9980A481-8A54-475A-B735-0C339FF30314" }, { "vulnerable": true, "criteria": "cpe:2.3:a:cisco:secure_client:*:*:*:*:*:windows:*:*", "versionEndExcluding": "5.0.02075", "matchCriteriaId": "7A856448-9BF4-4693-A1EA-3B6C06DB4259" } ] } ] } ], "references": [ { "url": "https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ac-csc-privesc-wx4U4Kw", "source": "ykramarz@cisco.com", "tags": [ "Vendor Advisory" ] } ] }
