How to Fix CVE-2023-0438

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

modoboa fixed: 2.0.4 
pip install modoboa>=2.0.4
Verify Direct and Transitive Dependencies

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

pip show modoboa

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2023-0438, inspect your installed packages using pip:

pip show modoboa

Analyze the terminal output to locate any version of Modoboa in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.0.4), your application is affected.

Note: The pip show modoboa command checks currently installed packages in your active Python environment.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
