GHSA-w6x2-jg8h-p6mp: Path Traversal in TYPO3 File Abstraction Layer Storages
Problem
Configurable storages using the local driver of the File Abstraction Layer (FAL) could be configured to access directories outside of the root directory of the corresponding project. The system setting in BE/lockRootPath was not evaluated by the file abstraction layer component. An administrator-level backend user account is required to exploit this vulnerability.
Solution
Update to TYPO3 versions 8.7.57 ELTS, 9.5.46 ELTS, 10.4.43 ELTS, 11.5.35 LTS, 12.4.11 LTS, 13.0.1 that fix the problem described.
ℹ️ Strong security defaults - Manual actions required
see Important: #102800 changelog
Assuming that a web project is located in the directory /var/www/example.org (the “project root path” for Composer-based projects) and the publicly accessible directory is located at /var/www/example.org/public (the “public root path”), accessing resources via the File Abstraction Layer component is limited to the mentioned directories.
To grant additional access to directories, they must be explicitly configured in the system settings of $GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] - either using the Install Tool or according to deployment techniques. The existing setting has been extended to support multiple directories configured as an array of strings.
Example:
$GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] = [
‘/var/shared/documents/’,
‘/var/shared/images/’,
];
❗ Storages that reference directories not explicitly granted will be marked as “offline” internally - no resources can be used in the website’s frontend and backend context.

In TYPO3 11.5.24, the filelist component allows attackers (who have access to the administrator panel) to read arbitrary files via directory traversal in the baseuri field, as demonstrated by POST `/typo3/record/edit` with `../../../ in data[sys_file_storage]*[data][sDEF][lDEF][basePath][vDEF]`.
TYPO3 version 11.5.24 suffers from a path traversal vulnerability.
