Loading vulnerability…
A buffer overflow vulnerability exists in the FTP client component of LabF nfsAxe version 3.7. The vulnerability is triggered when a remote FTP server sends an excessively long reply, which is not properly handled by the client, leading to a buffer overflow condition. This can allow an attacker controlling a malicious FTP server to execute arbitrary code on the client system.

This repository contains a single Metasploit module (modules/exploits/windows/ftp/labf_nfsaxe.rb) that exploits a stack buffer overflow vulnerability (CVE-2017-18047) in the LabF nfsAxe 3.7 FTP Client for Windows. The exploit works by running a malicious FTP server (using the Metasploit framework) that delivers a specially crafted response to the client. When a vulnerable client connects, the server sends a long directory string containing the attacker's payload, which overflows the stack and allows arbitrary code execution on the client system. The module is configurable for the attacker's IP and port, and supports standard Metasploit payloads. The only network endpoint is the attacker's FTP server (default 0.0.0.0:21), which the victim must connect to. The code is operational and ready for use within the Metasploit framework.
This repository is a comprehensive collection of exploit and proof-of-concept (PoC) code targeting a variety of vulnerabilities across multiple platforms and products. The structure is organized into directories for HEVD (HackSysExtremeVulnerableDriver) kernel exploits (covering stack overflow, use-after-free, arbitrary write, type confusion, race condition, and stack overflow with GS), Metasploit modules (for erlang cookie RCE, pfSense graph injection, SyncBreeze buffer overflow), personal exploits (for DELL EMC OneFS, Nimsoft nimcontroller, SyncBreeze, Sysdig Monitor, VXSearch), and ported exploits (for Oracle 9i XDB, Allied Telesyn AT-TFTP, LabF nfsAxe, Jenkins, Allok AVI, MySQL UDF, and WebDAV). The main capabilities include local and remote privilege escalation, remote code execution, and information disclosure. The exploits use a variety of payloads, including custom shellcode, msfvenom-generated payloads, and ROP chains, and target both local and network attack vectors. Notable fingerprintable endpoints include device handles (e.g., \\.\HackSysExtremeVulnerableDriver), HTTP/FTP services, and specific file paths (e.g., .zshrc for persistence). The repository demonstrates advanced exploitation techniques and is suitable for research, education, and penetration testing purposes.
