DATAC RealWin SCADA Server 2 On_FC_CONNECT_FCS_a_FILE Buffer Overflow

Description

This module exploits a vulnerability found in DATAC Control International RealWin SCADA Server 2.1 and below. By supplying a specially crafted On_FC_BINFILE_FCS_*FILE packet via port 910, RealWin will try to create a file (which would be saved to C:\Program Files\DATAC\Real Win\RW-version\filename) by first copying the user- supplied filename with an inline memcpy routine without proper bounds checking, which results a stack-based buffer overflow, allowing arbitrary remote code execution. Tested version: 2.0 (Build 6.1.8.10)

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
