Prowler是Prowler组织开源的一个网络安全审计工具。 Prowler 5.36.0之前版本存在命令注入漏洞，该漏洞源于Kubernetes provider连接测试仅检查exec块，未对kubeconfig_content中的legacy gcp auth-provider的config.cmd-path和config.cmd-args进行充分验证，导致攻击者提供的命令通过subprocess.Popen执行，可能导致命令注入。

Vulnerability Title
Prowler: RCE on Prowler App workers via kubeconfig auth-provider cmd-path
Source: CVE Program / CVE List V5
Vulnerability Description
Prowler is a cloud security platform. Prior to 5.36.0, the Kubernetes provider connection test accepted kubeconfig_content containing a legacy gcp auth-provider with config.cmd-path and config.cmd-args because kubeconfig_contains_exec_auth in api/src/backend/api/v1/serializers.py checked only exec blocks, and POST /api/v1/providers/{id}/connection loaded it through config.load_kube_config_from_dict in prowler/providers/kubernetes/kubernetes_provider.py, causing kubernetes-python CommandTokenSource.token to run the attacker-supplied command through subprocess.Popen on the shared worker. This issue is fixed in version 5.36.0.
