OS command injection in Fortinet FortiSandbox Cloud 5.0.4 allows remote authenticated users to execute commands via crafted HTTP requests. The WEB UI's vmimages update feature passes request content to an OS command without neutralizing command elements. Exploitation requires a super-admin profile and CLI access; successful requests run unauthorized code or commands on the service.
