/exploit - Exploit Generation

Generate exploit templates and payloads for identified vulnerabilities.

Usage

code

/exploit <vulnerability_type> [options]

Vulnerability Types

Buffer Overflow

code

/exploit buffer-overflow
/exploit bof

Generate pwntools template with:

•Offset finding (cyclic pattern)
•Return address overwrite
•Shellcode or ROP chain placeholder

Format String

code

/exploit format-string
/exploit fmt

Generate template with:

•Leak stack addresses
•Arbitrary write primitives
•GOT overwrite helpers

Heap Exploitation

code

/exploit heap
/exploit use-after-free
/exploit double-free

Generate template with:

•Heap layout manipulation
•Tcache/fastbin attack structures
•House of X techniques

ROP Chain

code

/exploit rop
/exploit ret2libc

Generate template with:

•Gadget finding
•Libc leak
•System/execve chain

SQL Injection

code

/exploit sqli

Generate payloads for:

•Union-based
•Boolean-based blind
•Time-based blind
•Error-based

XSS

code

/exploit xss

Generate payloads for:

•Reflected XSS
•Stored XSS
•DOM-based XSS

SSTI

code

/exploit ssti

Generate payloads for:

•Jinja2
•Twig
•Freemarker

Instructions

When the user invokes /exploit:

•
Identify the vulnerability type from the argument
•
Load the appropriate template from templates/
•
Customize based on context:
- •If binary exists, extract addresses/offsets
- •If architecture known, adjust payload
- •If protections known, adapt technique
•
Generate exploit script with:
- •Clear comments explaining each step
- •Debug helpers (gdb attach, logging)
- •Local and remote modes
- •Error handling
•
Save to exploits/ directory with descriptive name

Template Structure

All exploit templates should include:

python

#!/usr/bin/env python3
"""
Exploit: <challenge_name>
Type: <vulnerability_type>
Author: Generated by CTF Solver
"""

from pwn import *

# Configuration
BINARY = './challenge'
HOST = 'host'
PORT = 1337

# Setup
context.binary = ELF(BINARY)
context.log_level = 'debug'  # Change to 'info' for cleaner output

def exploit(io):
    """Main exploitation logic"""
    # TODO: Implement exploit
    pass

if __name__ == '__main__':
    if args.REMOTE:
        io = remote(HOST, PORT)
    elif args.GDB:
        io = gdb.debug(BINARY, '''
            break main
            continue
        ''')
    else:
        io = process(BINARY)

    exploit(io)
    io.interactive()

Output

After generating:

•Display the exploit code
•Explain key sections

•Provide usage instructions:

bash

python exploit.py          # Local
python exploit.py REMOTE   # Remote
python exploit.py GDB      # Debug
