- Issue
- A vulnerability exists in the Kubernetes C client where the certificate validation logic accepts properly constructed certificates from any Certificate Authority (CA) without properly verifying the trust chain. This flaw allows a malicious actor to present a forged certificate and potentially intercept or manipulate communication with the Kubernetes API server, leading to possible man-in-the-middle attacks and API impersonation.
Recommended action: Upgrade to 17.0.14 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
