How to Fix CVE-2019-17110

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.

github.com/kubernetes/kube-state-metrics fixed: 1.7.2 
Upgrade github.com/kubernetes/kube-state-metrics to 1.7.2
k8s.io/kube-state-metrics fixed: 1.7.2 
Upgrade k8s.io/kube-state-metrics to 1.7.2
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/kubernetes/kube-state-metrics

How to Check if You Are Affected

To determine whether your application is affected by CVE-2019-17110, inspect your project dependencies for Duplicate Advisory:

inspect dependencies for github.com/kubernetes/kube-state-metrics

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 1.7.2), 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-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 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# Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-c92w-72c5-9x59. This link is maintained to preserve external references. # Original Description A security issue was discovered in kube-state-metrics 1.7.x before 1.7.2. An experimental feature was added to v1.7.0 and v1.7.1 that enabled annotations to be exposed as metrics. By default, kube-state-metrics metrics only expose metadata about Secrets. However, a combination of the default kubectl behavior and this new feature can cause the entire secret content to end up in metric labels, thus inadvertently exposing the secret content in metrics.
