How to Fix CVE-2013-2217

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

suds fixed: 1.0.0 
pip install suds>=1.0.0
suds-py3 fixed: 1.4.4.1 
pip install suds-py3>=1.4.4.1
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 suds

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-2217, inspect your installed packages using pip:

pip show suds

Analyze the terminal output to locate any version of Suds in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.0.0), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-59: Improper Link Resolution Before File Access ('Link Following'), where the product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource. In Suds, 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

cache.py in Suds 0.4, when tempdir is set to None, allows local users to redirect SOAP queries and possibly have other unspecified impact via a symlink attack on a cache file with a predictable name in /tmp/suds/.
