Denial of Service in Siemens EN100 Ethernet module via UDP port 50000

This repository provides two exploit implementations (Python script and Metasploit module) for CVE-2015-5374, a denial of service vulnerability affecting Siemens SIPROTEC 4 and SIPROTEC Compact EN100 Ethernet Modules with firmware versions below V4.25. The exploit works by sending a specially crafted UDP packet to port 50000 of the target device, causing it to crash and require a manual reboot. The Python script (Siemens_SIPROTEC_DoS.py) is a standalone exploit that takes the target IP as an argument and sends the malicious packet. The Metasploit module (siemens_siprotec4.rb) integrates with the Metasploit Framework, allowing for easier exploitation and automation. Both implementations use the same payload and target the same network vector. The repository is well-structured, with a README.md providing usage instructions, background, and references. No hardcoded IPs or domains are present; the only fingerprintable endpoint is the UDP port 50000 on the target device.
