CVE-2011-1563 describes multiple stack-based buffer overflow vulnerabilities in the HMI application of DATAC RealFlex RealWin version 2.1 (Build 6.1.10.10) and earlier. The vulnerabilities are triggered by sending specially crafted packets to port 910, including a long username in an On_FC_CONNECT_FCS_LOGIN packet and various other crafted packets (e.g., On_FC_CTAGLIST_FCS_CADDTAG, On_FC_RFUSER_FCS_LOGIN, etc.). These overflows allow remote attackers to execute arbitrary code on the affected system.

This repository contains a single Metasploit module targeting a stack-based buffer overflow vulnerability (CVE-2011-1563) in DATAC Control International RealWin SCADA Server version 2.1 and below. The exploit works by sending a specially crafted On_FC_BINFILE_FCS_*FILE packet to TCP port 910, which triggers the vulnerable memcpy routine in the RealWin service. The module allows the attacker to execute arbitrary code on the target system with the privileges of the RealWin process. The payload is customizable (up to 450 bytes) and avoids specific bad characters. The exploit is operational and can be used to gain remote code execution on vulnerable systems. The repository is structured as a single Ruby file compatible with the Metasploit framework, and it includes all necessary exploit logic and payload handling.
This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability in DATAC Control International RealWin SCADA Server version 2.1 (Build 6.0.10.10) or earlier (CVE-2011-1563). The exploit works by sending a specially crafted On_FC_CONNECT_FCS_LOGIN packet with an overly long username to the service's default TCP port 910, triggering a buffer overflow and allowing arbitrary code execution via SEH overwrite. The module is written in Ruby and leverages Metasploit's payload generation and delivery mechanisms, allowing the attacker to execute a payload of their choice (e.g., reverse shell, meterpreter) on the target Windows system. The exploit is operational and requires the target service to be accessible over the network. The only notable endpoints are the TCP port 910 and the use of FlexMLang.dll for the SEH return address. The repository is structured as a single Metasploit module file.
