🎯 What You'll Learn
- Recognise when an SEH overwrite is required
- Overwrite the SEH chain reliably
- Find and use a POP/POP/RET gadget
- Stage and reach your shellcode
Overview
Many Windows applications cannot be exploited with a simple return-address overwrite. This lab teaches the SEH overwrite technique: corrupting the exception-handler chain and redirecting execution through POP/POP/RET gadgets.
Core Topics
- The Windows SEH chain
- nSEH / SEH overwrite
- POP POP RET gadgets
- Short and conditional jumps to shellcode
Prerequisites
A working KaliRange lab environment and comfort with the Linux command line.
Recommended Workflow
- Spin up the target in your KaliRange lab environment and confirm connectivity.
- Enumerate the target thoroughly before touching any exploit — information first.
- Reproduce each technique by hand so you understand why it works, not just the command.
- Capture evidence (commands, output, screenshots) as you go.
- Write a short note on how a defender would detect or prevent what you just did.
Only ever run these techniques against systems you own or have explicit written permission to test. Practise inside your own KaliRange lab.
Your Goal
Work through every task in your own lab, document your findings as you would on a real engagement, then note the defensive takeaways.
