Fortinet FortiClient EMS API Certificate Authentication Bypass Vulnerability Webapp Exploit

This module uses a pre-authentication access-control bypass in the API of Fortinet FortiClient EMS. The module will use the vulnerability by impersonating the trusted component that normally reports a successfully verified client TLS certificate. The module will check if the target is vulnerable to the authentication bypass by sending crafted HTTP requests to the /api/v1/system/capabilities endpoint. If the target is vulnerable, the module will log and output the value returned by the /api/v1/system/version endpoint.
