A stack-based buffer overflow exists in the CmpWebServer component of 3S CoDeSys 3.4 SP4 Patch 2 and earlier, as used in ABB AC500 PLC and potentially other products. The vulnerability is triggered by sending a long URI to TCP port 8080, allowing remote attackers to execute arbitrary code. The issue is due to improper bounds checking when handling HTTP requests, leading to overwriting of stack memory.

This repository contains a single Metasploit module targeting a remote stack buffer overflow vulnerability (CVE-2011-5007) in the 3S-Smart Software Solutions CoDeSys Scada Web Server (version 1.1.9.9, 3.4 SP4 Patch 2 and earlier) running on Windows XP SP3. The exploit works by sending a specially crafted HTTP GET request to the web server (default TCP port 8080), overflowing a stack buffer and allowing arbitrary code execution. The module supports two specific targets (v2.3 and v3.4 SP4 Patch 2), each with its own buffer offset and return address. The payload is customizable and can be any Metasploit-compatible Windows payload up to 650 bytes, with certain bad characters filtered. The module includes a check method to detect the presence of the vulnerable web server but cannot confirm the version. The exploit is operational and can be used to gain remote code execution on vulnerable systems. No hardcoded IP addresses or domains are present; the exploit is generic and targets the specified product and version via network access.
