Summary
AlanWeb SCADA does not enforce authorization for some directories. This allows an unauthorized attacker to read all files in these directories and even execute some of them. Critically the attacker could run PHP scripts directly on the connected database.
This issue was fixed in AlanWeb SCADA version 9.8.5
