ScadaLTS 2.8.1-release-candidate build 0 is affected by anĀ Authenticated Remote Code Execution via Scripting Sandbox Bypass

The DWR "DataSourceEditDwr" class exposes the "validateScript" method that compiles and executes attacker-supplied JavaScript via the Rhino scripting engine. There are no authorization checks on this method and so it is possible for an attacker with access to a low privilege user to abuse this flaw by leveraging the DWR routing bypass.
