How to Fix CVE-2013-0294

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

pyrad fixed: 2.1 
pip install pyrad>=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 pyrad

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-0294, inspect your installed packages using pip:

pip show pyrad

Analyze the terminal output to locate any version of Pyrad in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.1), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-330: Use of Insufficiently Random Values, where the product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. In Pyrad, 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

packet.py in pyrad before 2.1 uses weak random numbers to generate RADIUS authenticators and hash passwords, which makes it easier for remote attackers to obtain sensitive information via a brute force attack.
