This Metasploit module leverages an unauthenticated server-side template injection vulnerability in CrushFTP < 10.7.1 and < 11.1.0 (as well as legacy 9.x versions). Attackers can submit template injection payloads to the web API without authentication. When attacker payloads are reflected in the servers responses, the payloads are evaluated. The primary impact of the injection is arbitrary file read as root, which can result in authentication bypass, remote code execution, and NetNTLMv2 theft (when the host OS is Windows and SMB egress traffic is permitted).
