How to Fix CVE-2011-4103

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

django-piston fixed: 0.2.2.1
pip install django-piston>=0.2.2.1
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 django-piston

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2011-4103, inspect your installed packages using pip:

pip show django-piston

Analyze the terminal output to locate any version of Django piston in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.2.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Django piston, 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

emitters.py in Django Piston before 0.2.3 and 0.2.x before 0.2.2.1 does not properly deserialize YAML data, which allows remote attackers to execute arbitrary Python code via vectors related to the yaml.load method. Django Tastypie has a very similar vulnerability.
