{"id":"GHSA-r9vc-jfmh-6j48","aliases":[],"title":"TYPO3 frontend login vulnerable to Session Fixation","description":"It has been discovered that TYPO3 is susceptible to session fixation. If a user authenticates while anonymous session data is present, the session id is not changed. This makes it possible for attackers to generate a valid session id, trick users into using this session id (e.g. by leveraging a different Cross-Site Scripting vulnerability) and then maybe getting access to an authenticated session.","severity":"high","score":7.1,"published":"2024-05-30T21:04:40.000Z","modified":"2024-12-05T05:53:06.808Z","withdrawn":false,"knownExploited":false,"affected":[{"ecosystem":"Packagist","name":"typo3/cms","ranges":[{"events":[{"introduced":"6.2.0"},{"fixed":"6.2.14"}],"type":"ECOSYSTEM"}],"versions":["6.2.0","6.2.1","6.2.10","6.2.10-rc1","6.2.11","6.2.12","6.2.13","6.2.2","6.2.3","6.2.4","6.2.5","6.2.6","6.2.7","6.2.8","6.2.9"],"fixed":["6.2.14"]},{"ecosystem":"Packagist","name":"typo3/cms","ranges":[{"events":[{"introduced":"7.0.0"},{"fixed":"7.3.1"}],"type":"ECOSYSTEM"}],"versions":["7.0.0","7.0.1","7.0.2","7.1.0","7.2.0","7.3.0"],"fixed":["7.3.1"]}],"references":["https://github.com/TYPO3/typo3/commit/4c9aba94a930d56ab374693c9c5cc0458587278a","https://github.com/TYPO3/typo3/commit/4f6e84bba3c13ea8b2652af1a4c47758aa0705f4","https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/2015-07-01-2.yaml","https://github.com/TYPO3/typo3","https://typo3.org/security/advisory/typo3-core-sa-2015-003","https://typo3.org/teams/security/security-bulletins/typo3-core/typo3-core-sa-2015-003"],"sources":[{"name":"OSV","id":"GHSA-r9vc-jfmh-6j48","modified":"2024-12-05T05:53:06.808900Z","url":"https://osv.dev/vulnerability/GHSA-r9vc-jfmh-6j48"}],"assessments":[{"source":"OSV","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:N","score":7.1}]}
