{"id":"BIT-typo3-2020-15099","details":"In TYPO3 CMS greater than or equal to 9.0.0 and less than 9.5.20, and greater than or equal to 10.0.0 and less than 10.4.6, in a case where an attacker manages to generate a valid cryptographic message authentication code (HMAC-SHA1) - either by using a different existing vulnerability or in case the internal encryptionKey was exposed - it is possible to retrieve arbitrary files of a TYPO3 installation. This includes the possibility to fetch typo3conf/LocalConfiguration.php, which again contains the encryptionKey as well as credentials of the database management system being used. In case a database server is directly accessible either via internet or in a shared hosting network, this allows the ability to completely retrieve, manipulate or delete database contents. This includes creating an administration user account - which can be used to trigger remote code execution by injecting custom extensions. This has been patched in versions 9.5.20 and 10.4.6.","aliases":["CVE-2020-15099","GHSA-3x94-fv5h-5q2c"],"modified":"2024-03-06T11:25:28.861Z","published":"2024-03-06T11:11:45.190Z","database_specific":{"cpes":["cpe:2.3:a:typo3:typo3:*:*:*:*:*:*:*:*"],"severity":"High"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/TYPO3.CMS/security/advisories/GHSA-3x94-fv5h-5q2c"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2020-007"}],"affected":[{"package":{"name":"typo3","ecosystem":"Bitnami","purl":"pkg:bitnami/typo3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.5.20"},{"introduced":"10.0.0"},{"fixed":"10.4.6"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/typo3/BIT-typo3-2020-15099.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.7.3"}
