How to Fix CVE-2016-6186

To remediate this vulnerability, upgrade all affected Django 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 fixed: 1.8.14

pip install Django>=1.8.14

Django fixed: 1.9.8

pip install Django>=1.9.8

Django fixed: 1.10rc1

pip install Django>=1.10rc1

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

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2016-6186, inspect your installed packages using pip:

pip show Django

Analyze the terminal output to locate any version of Django in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.8.14), your application is affected.

Note: The pip show Django 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 Django, 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

Cross-site scripting (XSS) vulnerability in the `dismissChangeRelatedObjectPopup` function in `contrib/admin/static/admin/js/admin/RelatedObjectLookups.js` in Django before 1.8.14, 1.9.x before 1.9.8, and 1.10.x before 1.10rc1 allows remote attackers to inject arbitrary web script or HTML via vectors involving unsafe usage of Element.innerHTML.
