Buffer Overflow Exploitation

Purpose

Execute systematic buffer overflow vulnerability discovery and exploitation against Windows applications to achieve remote code execution. This skill enables comprehensive fuzzing to identify crashes, determination of EIP offset, bad character identification, JMP ESP location discovery, shellcode generation, and final exploit construction for penetration testing and OSCP-style assessments.

Inputs / Prerequisites

Required Tools

• Immunity Debugger with Mona.py plugin installed
• Python 2.7 for exploit script development
• Metasploit Framework (msfvenom, pattern_create, pattern_offset)
• Netcat for reverse shell listener
• Target Windows application with known vulnerability
