How to Fix CVE-2023-30451
To remediate this vulnerability, upgrade all affected Typo3/cms core dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade typo3/cms-core to 8.7.57
Upgrade typo3/cms-core to 9.5.46
Upgrade typo3/cms-core to 10.4.43
Upgrade typo3/cms-core to 11.5.35
Upgrade typo3/cms-core to 12.4.11
Upgrade typo3/cms-core to 13.0.1
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for typo3/cms-core
How to Check if You Are Affected
To determine whether your application is affected by CVE-2023-30451, inspect your project dependencies for Typo3/cms core:
inspect dependencies for typo3/cms-core
Analyze the terminal output to locate any version of Typo3/cms core in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 8.7.57), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), where the product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. In Typo3/cms core, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

"details" : "### Problem\nConfigurable 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.\n\n### Solution\nUpdate 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.\n\n#### ℹ️ **Strong security defaults - Manual actions required**\n\n_see [Important: #102800 changelog](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/11.5.x/Important-102800-FileAbstractionLayerEnforcesAbsolutePathsToMatchProjectRootOrLockRootPath.html)_\n\nAssuming 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.\n\nTo grant additional access to directories, they must be explicitly configured in the system settings of `$GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath']` - either using the Install Tool or according to deployment techniques. The existing setting has been extended to support multiple directories configured as an array of strings.\n\nExample:\n```php\n$GLOBALS['TYPO3_CONF_VARS']['BE']['lockRootPath'] = [\n ‘/var/shared/documents/’,\n ‘/var/shared/images/’,\n];\n```\n\n❗ **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.**\n\n### Credits\nThanks to TYPO3 core & security team members Oliver Hader and Benjamin Franzke who fixed the issue.\n\n### References\n* [TYPO3-CORE-SA-2024-001](https://typo3.org/security/advisory/typo3-core-sa-2024-001)\n",
