How to Fix CVE-2013-2132

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

pymongo fixed: 2.5.2 
pip install pymongo>=2.5.2
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 pymongo

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-2132, inspect your installed packages using pip:

pip show pymongo

Analyze the terminal output to locate any version of Pymongo in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.5.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-395: Use of NullPointerException Catch to Detect NULL Pointer Dereference, where catching nullpointerexception should not be used as an alternative to programmatic checks to prevent dereferencing a null pointer. In Pymongo, 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

bson/_cbsonmodule.c in the mongo-python-driver (aka. pymongo) before 2.5.2, as used in MongoDB, allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to decoding of an "invalid DBRef."
