How to Fix CVE-2020-1764

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

github.com/kiali/kiali fixed: 1.15.1 
Upgrade github.com/kiali/kiali to 1.15.1
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/kiali/kiali

How to Check if You Are Affected

To determine whether your application is affected by CVE-2020-1764, inspect your project dependencies for Github.com/kiali/kiali:

inspect dependencies for github.com/kiali/kiali

Analyze the terminal output to locate any version of Github.com/kiali/kiali in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.15.1), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-321: Use of Hard-coded Cryptographic Key, where the product uses a hard-coded, unchangeable cryptographic key. In Github.com/kiali/kiali, 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 hard-coded cryptographic key vulnerability in the default configuration file was found in Kiali, all versions prior to 1.15.1. A remote attacker could abuse this flaw by creating their own JWT signed tokens and bypass Kiali authentication mechanisms, possibly gaining privileges to view and alter the Istio configuration.
