Description
The `/registercrd` endpoint in KubePlus 4.14 in the kubeconfiggenerator component is vulnerable to command injection. The component uses `subprocess.Popen()` with `shell=True` parameter to execute shell commands, and the user-supplied `chartName` parameter is directly concatenated into the command string without any sanitization or validation. An attacker can inject arbitrary shell commands by crafting a malicious `chartName` parameter value.
Affected configurations
• cloudark kubeplus (<= 4.2.0)
