CVE-2018-7756: Dewesoft

Critical severity, CVSS 9.8. EPSS: 60.7% chance of exploitation in the next 30 days.

RunExeFile.exe in the installer for DEWESoft X3 SP1 (64-bit) devices does not require authentication for sessions on TCP port 1999, which allows remote attackers to execute arbitrary code or access internal commands, as demonstrated by a RUN command that launches a .EXE file located at an arbitrary external URL, or a "SETFIREWALL Off" command.
