# Exploit Title: Green Hills INTEGRITY RTOS IPCOMShell TELNET Format String Full Chain - Realistic F-16 Ground Maintenance
# CVE: CVE-2019-7711
# Date: 2026-05-04
# Exploit Author: Mohammed Idrees Banyamer
# Author Country: Jordan
# Instagram: @banyamer_security
# Author GitHub: https://github.com/mbanyamer
# Vendor Homepage: https://www.ghs.com
# Software Link: N/A (Proprietary)
# Affected: Green Hills INTEGRITY RTOS 5.0.4 with Interpeak IPCOMShell - Used in F-16 Block 60 Color Display Processor (CDP) and mission systems
# Tested on: INTEGRITY RTOS 5.0.4 lab simulation (emulating avionics ground test environment)
# Category: Remote (Ground Maintenance)
# Platform: Embedded RTOS - Aerospace (F-16 Avionics)
# Exploit Type: Format String (Leak → Arbitrary Write → Potential Control Flow Hijack)
# CVSS: 6.8 (Medium-High in ground maintenance context)
# CWE : CWE-134 (Use of Externally-Controlled Format String)
# Description: The undocumented "prompt" command in IPCOMShell passes user-controlled input directly to printf(). 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.
