How to Fix CVE-2008-1937

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

moin fixed: 1.6.3 
pip install moin>=1.6.3
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 moin

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2008-1937, inspect your installed packages using pip:

pip show moin

Analyze the terminal output to locate any version of Moin in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.6.3), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-284: Improper Access Control, where the product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. In Moin, 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

The user form processing (userform.py) in MoinMoin before 1.6.3, when using ACLs or a non-empty superusers list, does not properly manage users, which allows remote attackers to gain privileges.
