{"id":"GHSA-8h4m-r4wm-xj7r","aliases":[],"url":"https://o3.security/vulnerability/GHSA-8h4m-r4wm-xj7r","summary":"TYPO3 Arbitrary Code Execution via File List Module","details":"Due to missing file extensions in $GLOBALS['TYPO3_CONF_VARS']['BE'][‘fileDenyPattern’], backend users are allowed to upload *.phar, *.shtml, *.pl or *.cgi files which can be executed in certain web server setups. A valid backend user account is needed in order to exploit this vulnerability.\n\nDerivatives of Debian GNU Linux are handling *.phar files as PHP applications since PHP 7.1 (for unofficial packages) and PHP 7.2 (for official packages).\n\nThe file extension *.shtml is bound to server side includes which are not enabled per default in most common Linux based distributions. File extension *.pl and *.cgi require additional handlers to be configured which is also not the case in most common distributions (except for /cgi-bin/ location).","published":"2024-06-07T18:32:42Z","modified":"2024-12-04T05:45:45.547191Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"8.7.23"},{"ecosystem":"Packagist","name":"typo3/cms","fixedVersion":"9.5.4"}],"fix":{"url":"https://github.com/TYPO3/typo3/commit/095ae4ab6869d0f7dc7befedb851cdd7ad0c7ebf","label":"TYPO3/typo3@095ae4a"},"references":[{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/095ae4ab6869d0f7dc7befedb851cdd7ad0c7ebf"},{"type":"WEB","url":"https://github.com/TYPO3/typo3/commit/9990278ce7cf8e4d6b8bf31edec6787722d38b0f"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms/2019-01-22-7.yaml"},{"type":"PACKAGE","url":"https://github.com/TYPO3/typo3"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2019-008"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2024-12-04T05:45:45.547191Z"}}
