{"id":"GHSA-r9vc-jfmh-6j48","aliases":[],"url":"https://o3.security/vulnerability/GHSA-r9vc-jfmh-6j48","summary":"TYPO3 frontend login vulnerable to Session Fixation","details":"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.","published":"2024-05-30T21:04:40Z","modified":"2024-12-05T05:53:06.808900Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"6.2.14"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"7.3.1"}],"fix":{"url":"https://github.com/TYPO3/typo3/commit/4c9aba94a930d56ab374693c9c5cc0458587278a","label":"TYPO3/typo3@4c9aba9"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/4c9aba94a930d56ab374693c9c5cc0458587278a"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/4f6e84bba3c13ea8b2652af1a4c47758aa0705f4"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/2015-07-01-2.yaml"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2015-003"},{"type":"WEB","url":"https://typo3.org/teams/security/security-bulletins/typo3-core/typo3-core-sa-2015-003"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-05T05:53:06.808900Z"}}
