🔗 Advanced Web Application Vulnerability Chain

This comprehensive penetration testing challenge focuses on chaining multiple web application vulnerabilities including IDOR, Zip Slip, and Server-Side Template Injection (SSTI). You'll need to exploit these vulnerabilities systematically to gain initial access, then leverage internal services and privilege escalation techniques for complete system compromise.

🎯 What You'll Learn
  • ✓ Insecure Direct Object Reference (IDOR) exploitation
  • ✓ Zip Slip vulnerability and file overwrite attacks
  • ✓ Server-Side Template Injection (SSTI) techniques
  • ✓ Internal service discovery and port forwarding
  • ✓ Backup service exploitation
  • ✓ Credential harvesting from system files
  • ✓ Sudo privilege escalation via vim
🔍 Challenge Overview

You'll encounter a blog application with hidden administrative features and internal backup services. The challenge requires exploiting IDOR to discover credentials, using Zip Slip to replace application code, leveraging SSTI for command execution, and escalating privileges through internal service exploitation.

Penetration Testing Context: This challenge demonstrates a realistic attack chain combining multiple web application vulnerabilities with internal service exploitation, representing common attack patterns found in enterprise web applications with administrative interfaces and backup systems.
