Description

This module exploits a vulnerability found on Siemens FactoryLink 8. The
vulnerability occurs when CSService.exe processes a CSMSG_ListFiles_REQ message,
the user-supplied path first gets converted to ANSI format (CodePage 0), and then
gets handled by a logging routine where proper bounds checking is not done,
therefore causing a stack-based buffer overflow, and results arbitrary code execution.
