php-8.1-dev-Exploit

⚠️ Important (read first)

This repository contains a Java proof-of-concept (PoC) intended for CTF / lab use only. Do not run this code against systems you do not own or do not have explicit written permission to test. Unauthorized exploitation is illegal. Use only in isolated environments (VMs, containers, private CTF/HTB boxes).

Prerequisites

  • Java JDK (8+) installed (javac and java in PATH)
  • Network connectivity between your attacking machine and the target (lab/CTF network)
  • A listener ready on your host to receive the reverse shell (e.g., nc -lvnp ), run in a separate terminal before attempting the PoC.
