Kerentanan Improper Certificate Validation. Skor CVSS 4.0 5.8 (Medium) menurut CNA.

Deskripsi (NVD)

When kuma-dp is started against an HTTPS control plane and the operator did not pass a CA certificate, the data plane connects with TLS peer verification disabled, and the dataplane authentication token is sent over that unverified connection. An on-path actor can intercept the dataplane authentication token and impersonate the control plane to the data plane, injecting a forged bootstrap configuration and taking over the proxy.
