How to Fix CVE-2013-7110

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

transifex-client fixed: 0.10 
pip install transifex-client>=0.10
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 transifex-client

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2013-7110, inspect your installed packages using pip:

pip show transifex-client

Analyze the terminal output to locate any version of Transifex client in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.10), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Transifex client, 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

Transifex command-line client before 0.10 does not validate X.509 certificates for data transfer connections, which allows man-in-the-middle attackers to spoof a Transifex server via an arbitrary certificate. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-2073.
