How to Fix CVE-2017-16764

To remediate this vulnerability, upgrade all affected Django make app 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_make_app fixed: Latest secure release 
pip install django_make_app>=Latest secure release
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_make_app

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2017-16764, inspect your installed packages using pip:

pip show django_make_app

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

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Django make app, 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

An exploitable vulnerability exists in the YAML parsing functionality in the `read_yaml_file` method in `io_utils.py` in django_make_app 0.1.3. A YAML parser can execute arbitrary Python commands resulting in command execution. An attacker can insert Python into loaded YAML to trigger this vulnerability.
