CyberRota Analysis

AI-Generated

Kubernetes versions prior to 3.9.0 are vulnerable to an argument injection flaw in structured tools, allowing attackers to bypass critical security checks. By injecting the --server flag, an attacker can redirect kubectl commands to a malicious API server, potentially exposing the operator's bearer token and leading to complete cluster compromise. Organizations using affected Kubernetes versions should prioritize immediate patching to mitigate this critical vulnerability.

Original NVD Description

MCP Server Kubernetes before 3.9.0 contains an argument injection vulnerability in structured tools (kubectl_get, kubectl_describe, kubectl_delete) that allows attackers to bypass the assertNoDangerousFlags security check by supplying resourceType and name parameters with leading dashes. Attackers can inject the --server flag to redirect kubectl commands to an attacker-controlled API server, causing the operator's bearer token to be transmitted externally and enabling full cluster compromise.
