{"id":"GHSA-gqqf-g5r7-84vf","summary":"TYPO3 HTML Sanitizer Bypasses Cross-Site Scripting Protection","details":"\u003e ### Meta\n\u003e * CVSS: `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:F/RL:O/RC:C` (5.7)\n\n### Problem\nDue to a parsing issue in upstream package [`masterminds/html5`](https://packagist.org/packages/masterminds/html5), malicious markup used in a sequence with special HTML comments cannot be filtered and sanitized. This allows to by-pass the cross-site scripting mechanism of [`typo3/html-sanitizer`](https://github.com/TYPO3/html-sanitizer).\n\n### Solution\nUpdate to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix the problem described above.\n\n### Credits\nThanks to David Klein who reported this issue, and to TYPO3 security team member Oliver Hader who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2022-011](https://typo3.org/security/advisory/typo3-core-sa-2022-011)\n* [GHSA-47m6-46mj-p235](https://github.com/TYPO3/html-sanitizer/security/advisories/GHSA-47m6-46mj-p235)\n","modified":"2024-12-06T05:37:17.196377Z","published":"2022-09-15T03:26:51Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2022-09-15T03:26:51Z","nvd_published_at":null,"cwe_ids":[],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/typo3/security/advisories/GHSA-gqqf-g5r7-84vf"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/d4f260570abd934fcf3819370a135bef33d729b7"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"}],"affected":[{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.0.0"},{"fixed":"7.6.58"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 7.6.57","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-gqqf-g5r7-84vf/GHSA-gqqf-g5r7-84vf.json"}},{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.0.0"},{"fixed":"8.7.48"}]}],"versions":["v8.7.10","v8.7.11","v8.7.12","v8.7.13","v8.7.14","v8.7.15","v8.7.16","v8.7.17","v8.7.18","v8.7.19","v8.7.20","v8.7.21","v8.7.22","v8.7.23","v8.7.24","v8.7.25","v8.7.26","v8.7.27","v8.7.28","v8.7.29","v8.7.30","v8.7.31","v8.7.32","v8.7.7","v8.7.8","v8.7.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-gqqf-g5r7-84vf/GHSA-gqqf-g5r7-84vf.json","last_known_affected_version_range":"\u003c= 8.7.47"}},{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.0"},{"fixed":"9.5.37"}]}],"versions":["v9.0.0","v9.1.0","v9.2.0","v9.2.1","v9.3.0","v9.3.1","v9.3.2","v9.3.3","v9.4.0","v9.5.0","v9.5.1","v9.5.10","v9.5.11","v9.5.12","v9.5.13","v9.5.14","v9.5.15","v9.5.16","v9.5.17","v9.5.18","v9.5.19","v9.5.2","v9.5.20","v9.5.21","v9.5.22","v9.5.23","v9.5.24","v9.5.25","v9.5.26","v9.5.27","v9.5.28","v9.5.29","v9.5.3","v9.5.30","v9.5.31","v9.5.4","v9.5.5","v9.5.6","v9.5.7","v9.5.8","v9.5.9"],"database_specific":{"last_known_affected_version_range":"\u003c= 9.5.36","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-gqqf-g5r7-84vf/GHSA-gqqf-g5r7-84vf.json"}},{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"10.0.0"},{"fixed":"10.4.32"}]}],"versions":["v10.0.0","v10.1.0","v10.2.0","v10.2.1","v10.2.2","v10.3.0","v10.4.0","v10.4.1","v10.4.10","v10.4.11","v10.4.12","v10.4.13","v10.4.14","v10.4.15","v10.4.16","v10.4.17","v10.4.18","v10.4.19","v10.4.2","v10.4.20","v10.4.21","v10.4.22","v10.4.23","v10.4.24","v10.4.25","v10.4.26","v10.4.27","v10.4.28","v10.4.29","v10.4.3","v10.4.30","v10.4.31","v10.4.4","v10.4.5","v10.4.6","v10.4.7","v10.4.8","v10.4.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-gqqf-g5r7-84vf/GHSA-gqqf-g5r7-84vf.json","last_known_affected_version_range":"\u003c= 10.4.31"}},{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"11.0.0"},{"fixed":"11.5.16"}]}],"versions":["v11.0.0","v11.1.0","v11.1.1","v11.2.0","v11.3.0","v11.3.1","v11.3.2","v11.3.3","v11.4.0","v11.5.0","v11.5.1","v11.5.10","v11.5.11","v11.5.12","v11.5.13","v11.5.14","v11.5.15","v11.5.2","v11.5.3","v11.5.4","v11.5.5","v11.5.6","v11.5.7","v11.5.8","v11.5.9"],"database_specific":{"last_known_affected_version_range":"\u003c= 11.5.15","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2022/09/GHSA-gqqf-g5r7-84vf/GHSA-gqqf-g5r7-84vf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
