Loading vulnerability…
A stack-based buffer overflow exists in the FTP service of 4D WebSTAR versions 5.3.2 and earlier. The vulnerability is triggered when a remote attacker sends an overly long FTP command, which overflows a stack buffer and allows for the execution of arbitrary code.

This repository contains a single Metasploit exploit module targeting a stack buffer overflow vulnerability in the WebSTAR FTP server running on Mac OS X 10.3.4-10.3.6 (PowerPC). The exploit works by sending a specially crafted USER command to the FTP service, overflowing a buffer in the server's logging routine and allowing for reliable code execution via a series of return address manipulations through the System library. The module allows for customizable payloads (up to 300 bytes, with certain bad characters), and upon successful exploitation, arbitrary code can be executed with elevated privileges on the target system. The only fingerprintable endpoint is the FTP service (typically port 21/tcp) on the target host. The exploit is operational and part of the Metasploit framework, making it easy to use and customize for penetration testing or red teaming against vulnerable systems.
