Loading vulnerability…
A stack-based buffer overflow exists in BKBCopyD.exe in Yokogawa CENTUM CS 3000 R3.09.50 and earlier. The vulnerability is triggered when the application processes a specially crafted TCP packet, leading to a buffer overflow condition on the stack. This can allow remote attackers to execute arbitrary code within the context of the vulnerable process.

This repository contains a single Metasploit exploit module targeting a stack-based buffer overflow vulnerability in the BKBCopyD.exe service of Yokogawa CENTUM CS 3000 R3.08.50 running on Windows XP SP3. The exploit works by sending a specially crafted TCP packet to port 20111, overflowing a buffer and overwriting the return address to execute arbitrary code. The module allows for customizable payloads up to 373 bytes, enabling actions such as spawning a shell or running a Meterpreter session. The code includes detection logic to check for the presence of the vulnerable service. The main fingerprintable endpoints are the TCP port 20111, the BKBCopyD.exe service, and the libBKBUtil.dll used for the return address. The repository is structured as a standard Metasploit module written in Ruby, and is operational, providing a working exploit for the specified vulnerability (CVE-2014-0784).
