How to Fix CVE-2023-39343

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

sulu/sulu fixed: 2.5.10 
Upgrade sulu/sulu to 2.5.10
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 sulu/sulu

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-39343, inspect your project dependencies for Sulu/sulu:

inspect dependencies for sulu/sulu

Analyze the terminal output to locate any version of Sulu/sulu in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.5.10), 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-204: Observable Response Discrepancy, where the product provides different responses to incoming requests in a way that reveals internal state information to an unauthorized actor outside of the intended control sphere. In Sulu/sulu, 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 It allows over the Admin Login form to detect which user (username, email) exists and which one do not exist. Impacted by this issue are Sulu installation >= 2.5.0 and <2.5.10 using the newer Symfony Security System which is default since Symfony 6.0 but can be enabled in Symfony 5.4. Sulu Installation not using the old Symfony 5.4 security System and previous version are not impacted by this Security issue. ### Patches The problem has been patched in version 2.5.10. ### Workarounds Create a custom AuthenticationFailureHandler which does not return the `$exception->getMessage();` instead the `$exception->getMessageKey();` ### References Currently no references.
