Root Cause Analysis
The vulnerability stemmed from Tiller's TLS configuration accepting self-signed client certificates. The critical change in the fix was modifying the ClientAuth
mode from VerifyClientCertIfGiven
to RequireAndVerifyClientCert
in the tlsOptions
function. This function controls TLS handshake behavior, and the original setting didn't enforce CA validation for client certificates, allowing improper validation. The commit diff explicitly shows this security-sensitive configuration change, directly addressing CWE-295.
