CyberRota Analysis

AI-Generated

Kumactl is vulnerable when an operator configures an HTTPS control plane profile without specifying a CA certificate, leading to disabled TLS verification and unencrypted transmission of API tokens. This flaw allows an attacker on the network path to intercept sensitive user or admin API tokens, potentially enabling unauthorized actions against the control plane. Organizations using kumactl should prioritize addressing this vulnerability to safeguard their API tokens and maintain secure control plane operations.

Original NVD Description

When an operator adds an HTTPS control plane profile to kumactl without providing a CA certificate, kumactl disables TLS verification and sends API tokens over the unverified connection. An attacker on the network path between the operator and the control plane can intercept user or admin API tokens and then act against the control plane as that user.
