DoS via Invalid FTP Commands in SEGGER FTP Server <3.22a

This repository contains a Python proof-of-concept exploit for CVE-2018-7449, targeting SEGGER embOS/IP FTP Server version 3.22. The exploit consists of two main code files: 'exploitFTPModule.py', which implements the core logic for interacting with the FTP server and sending malicious commands, and 'run-exploit.py', which serves as the entry point and handles argument parsing and execution flow. The exploit requires valid FTP credentials and a reachable FTP server (firewall disabled or compromised). Upon successful authentication, it sends a sequence of malformed FTP commands (STOR, LIST, RETR with crafted arguments) that cause the FTP daemon to crash, resulting in a denial of service. The README provides usage instructions and context, referencing the original exploit inspiration. No hardcoded IPs or credentials are present; the target and credentials are supplied at runtime. The exploit is not weaponized but serves as a functional proof-of-concept for the described vulnerability.
