{"id":"GHSA-f9hr-7cfq-mjg2","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).\n\n","modified":"2024-12-05T05:42:05.664259Z","published":"2024-05-30T16:13:05Z","database_specific":{"nvd_published_at":null,"cwe_ids":["CWE-434"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2024-05-30T16:13:05Z"},"references":[{"type":"WEB","url":"https://github.com/TYPO3-CMS/core/commit/45c311d120c359d54cc918e962c374e774239899"},{"type":"WEB","url":"https://github.com/TYPO3-CMS/core/commit/5095084efae471c5fef7b578f2bc8a5060e1e148"},{"type":"WEB","url":"https://github.com/FriendsOfPHP/security-advisories/blob/master/typo3/cms-core/2019-01-22-7.yaml"},{"type":"PACKAGE","url":"https://github.com/TYPO3-CMS/core"},{"type":"WEB","url":"https://typo3.org/security/advisory/typo3-core-sa-2019-008"}],"affected":[{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"8.0.0"},{"fixed":"8.7.23"}]}],"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","v8.7.7","v8.7.8","v8.7.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-f9hr-7cfq-mjg2/GHSA-f9hr-7cfq-mjg2.json"}},{"package":{"name":"typo3/cms-core","ecosystem":"Packagist","purl":"pkg:composer/typo3/cms-core"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"9.0.0"},{"fixed":"9.5.4"}]}],"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","v9.5.2","v9.5.3"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-f9hr-7cfq-mjg2/GHSA-f9hr-7cfq-mjg2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
