| タイトル | aiyiyi121 SxDevOps 1.1 Command Injection |
|---|
| 説明 | The TASK_RUN_COMMAND task type in SxDevOps passes payload.command directly to paramiko.SSHClient.exec_command() without any filtering or escaping. While the TASK_SERVICE_STATUS branch properly uses shlex.quote() for sanitization, this branch has zero filtering. Attackers with ops.task.execute permission can chain arbitrary commands using shell metacharacters (; && ||) to execute them on all SSH-managed target hosts. AIOps-generated tasks (TRIGGER_SOURCE_AIOPS) share the same vulnerability, expanding the attack surface through LLM prompt injection.
Vulnerable code in backend/ops/host_tasks.py lines 293, 589:
elif task_type == "TASK_RUN_COMMAND":
command = task_payload.get("command", "")
stdin, stdout, stderr = ssh_client.exec_command(command)
Compare with the properly sanitized TASK_SERVICE_STATUS branch:
service_name = shlex.quote(service_name)
command = f"systemctl status {service_name}"
Impact: Remote Code Execution on all SSH-managed hosts, enabling lateral movement across the entire infrastructure under management. |
