In affected versions failing to properly parse, sanitize and encode malicious rich-text content, the content rendering process in the website frontend is vulnerable to cross-site scripting. Corresponding rendering instructions via TypoScript functionality HTMLparser does not consider all potentially malicious HTML tag & attribute combinations per default. In default scenarios, a valid backend user account is needed to exploit this vulnerability. In case custom plugins used in the website frontend accept and reflect rich-text content submitted by users, no authentication is required. Update to TYPO3 versions 7.6.53 ELTS, 8.7.42 ELTS, 9.5.29, 10.4.19, 11.3.2 that fix the problem described."}]}, "problemtype": {"problemtype_data": [{"description": [{"lang": "en", "value": "CWE-79"}]}]}, "data_version": "4.0", "CVE_data_meta": {"ID": "CVE-2021-32768", "ASSIGNER": "security-advisories@github.com"}}, "impact": {"baseMetricV2": {"cvssV2": {"version": "2.0", "baseScore": 4.3, "accessVector": "NETWORK", "vectorString": "AV:N/AC:M/Au:N/C:N/I:P/A:N", "authentication": "NONE", "integrityImpact": "PARTIAL", "accessComplexity": "MEDIUM", "availabilityImpact": "NONE", "confidentialityImpact": "NONE"}, "severity": "MEDIUM", "acInsufInfo": false, "impactScore": 2.9, "obtainAllPrivilege": false, "exploitabilityScore": 8.6, "obtainUserPrivilege": false, "obtainOtherPrivilege": false, "userInteractionRequired": true}, "baseMetricV3": {"cvssV3": {"scope": "CHANGED", "version": "3.1", "baseScore": 6.1, "attackVector": "NETWORK", "baseSeverity": "MEDIUM", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N", "integrityImpact": "LOW", "userInteraction": "REQUIRED", "attackComplexity": "LOW", "availabilityImpact": "NONE", "privilegesRequired": "NONE", "confidentialityImpact": "LOW"}, "impactScore": 2.7, "exploitabilityScore": 2.8}}, "publishedDate": "2021-08-10T17:15Z", "configurations": {"nodes": [{"children": [], "operator": "OR", "cpe_match": [{"cpe23Uri": "cpe:2.3:a:typo3:typo3:*:*:*:*:elts:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "7.6.52", "versionStartIncluding": "7.0.0"}, {"cpe23Uri": "cpe:2.3:a:typo3:typo3:*:*:*:*:elts:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "8.7.41", "versionStartIncluding": "8.0.0"}, {"cpe23Uri": "cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "9.5.28", "versionStartIncluding": "9.0.0"}, {"cpe23Uri": "cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "10.4.18", "versionStartIncluding": "10.0.0"}, {"cpe23Uri": "cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*", "cpe_name": [], "vulnerable": true, "versionEndIncluding": "11.3.1", "versionStartIncluding": "11.0.0"}]}], "CVE_data_version": "4.0"}, "lastModifiedDate": "2021-08-19T15:51Z"}
