Description

This module exploits a remote stack buffer overflow vulnerability in ABB MicroSCADA. The
issue is due to the handling of unauthenticated EXECUTE operations on the wserver.exe
component, which allows arbitrary commands. The component is disabled by default, but
required when a project uses the SCIL function WORKSTATION_CALL.

This module has been tested successfully on ABB MicroSCADA Pro SYS600 9.3 on
Windows XP SP3 and Windows 7 SP1.
