How to Fix GHSA-27jc-jmp8-qfw5

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

keylime fixed: 7.12.2 
pip install keylime>=7.12.2
keylime fixed: 7.13.1 
pip install keylime>=7.13.1
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 keylime

How to Check if You Are Affected

To determine whether your Python environment is affected by GHSA-27jc-jmp8-qfw5, inspect your installed packages using pip:

pip show keylime

Analyze the terminal output to locate any version of Duplicate Advisory in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.12.2), your application is affected.

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

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-322: Key Exchange without Entity Authentication, where the product performs a key exchange with an actor without verifying the identity of that actor. In Duplicate Advisory, 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

### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-4jqp-9qjv-57m2. This link is maintained to preserve external references. ### Original Description A flaw was found in Keylime. The Keylime registrar, since version 7.12.0, does not enforce client-side Transport Layer Security (TLS) authentication. This authentication bypass vulnerability allows unauthenticated clients with network access to perform administrative operations, including listing agents, retrieving public Trusted Platform Module (TPM) data, and deleting agents, by connecting without presenting a client certificate.
