Nagios XI versions prior to 5.4.13 contain a remote code execution vulnerability in the Component Download page. The download/import handler used unsafe command construction with attacker-controlled input and lacked sufficient validation and output encoding, allowing an authenticated user to inject commands or otherwise execute arbitrary code with the privileges of the application service.
