How to Fix CVE-2020-36660

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

EVE-SRP fixed: 0.12.12 
pip install EVE-SRP>=0.12.12
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 EVE-SRP

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2020-36660, inspect your installed packages using pip:

pip show EVE-SRP

Analyze the terminal output to locate any version of EVE SRP in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.12.12), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-200: Exposure of Sensitive Information to an Unauthorized Actor, where the product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. In EVE SRP, 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

A vulnerability was found in paxswill EVE Ship Replacement Program 0.12.11. It has been rated as problematic. This issue affects some unknown processing of the file src/evesrp/views/api.py of the component User Information Handler. The manipulation leads to information disclosure. The attack may be initiated remotely. Upgrading to version 0.12.12 is able to address this issue. The name of the patch is 9e03f68e46e85ca9c9694a6971859b3ee66f0240.
