How to Fix CVE-2015-5285

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

kallithea fixed: 0.3 
pip install kallithea>=0.3
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 kallithea

How to Check if You Are Affected

To determine whether your Python environment is affected by CVE-2015-5285, inspect your installed packages using pip:

pip show kallithea

Analyze the terminal output to locate any version of Kallithea in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.3), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-93: Improper Neutralization of CRLF Sequences ('CRLF Injection'), where the product uses crlf (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes crlf sequences from inputs. In Kallithea, 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

CRLF injection vulnerability in Kallithea before 0.3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via the `came_from` parameter to `_admin/login`.
