To remediate this vulnerability, upgrade all affected Github.com/kubernetes/kubernetes dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade github.com/kubernetes/kubernetes to 1.25.4Upgrade github.com/kubernetes/kubernetes to 1.24.8Upgrade github.com/kubernetes/kubernetes to 1.23.14Upgrade github.com/kubernetes/kubernetes to 1.22.16Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for github.com/kubernetes/kubernetesHow to Check if You Are Affected
To determine whether your application is affected by CVE-2022-3162, inspect your project dependencies for Github.com/kubernetes/kubernetes:
inspect dependencies for github.com/kubernetes/kubernetesAnalyze the terminal output to locate any version of Github.com/kubernetes/kubernetes in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 1.25.4), 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-23: Relative Path Traversal, where the product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory. In Github.com/kubernetes/kubernetes, 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.
