How to Fix CVE-2010-2970

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: 1.9.3 
pip install Moin>=1.9.3
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-2010-2970, 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 1.9.3), 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-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 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

Multiple cross-site scripting (XSS) vulnerabilities in MoinMoin 1.9.x before 1.9.3 allow remote attackers to inject arbitrary web script or HTML via crafted content, related to (1) action/SlideShow.py, (2) action/anywikidraw.py, and (3) action/language_setup.py, a similar issue to CVE-2010-2487.
