How to Fix CVE-2024-28190

To remediate this vulnerability, upgrade all affected Contao dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

contao/core-bundle fixed: 4.13.40
Upgrade contao/core-bundle to 4.13.40
contao/core-bundle fixed: 5.3.4
Upgrade contao/core-bundle to 5.3.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for contao/core-bundle

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-28190, inspect your project dependencies for Contao:

inspect dependencies for contao/core-bundle

Analyze the terminal output to locate any version of Contao in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.13.40), 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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting'), where the product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. In Contao, 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.

Source Advisory Statement

### Impact Users can insert malicious code into file names when uploading files, which is then executed in tooltips and popups in the backend. ### Patches Update to Contao 4.13.40 or Contao 5.3.4. ### Workarounds Disable uploads for untrusted users. ### References https://contao.org/en/security-advisories/cross-site-scripting-in-the-file-manager ### For more information If you have any questions or comments about this advisory, open an issue in [contao/contao](https://github.com/contao/contao/issues/new/choose). ### Credits Thanks to Alexander Wuttke for reporting this vulnerability.
