This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from cloudark. Update kubeplus to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
