🔍 How to Verify
Check if Vulnerable:
Check if system is running SourceCodester Purchase Order Management System v1.0 by examining source code or version filesCheck Version:
Check for version information in source code files or database configurationVerify Fix Applied:
Test if /admin?page=user endpoint no longer accepts malicious input or has been properly secured📡 Detection & Monitoring
Log Indicators:
- Unusual requests to /admin?page=user with suspicious parameters
- Multiple failed login attempts followed by successful admin access
- Unexpected file uploads or system command execution
Network Indicators:
- HTTP requests containing shell commands or encoded payloads in /admin?page=user parameters
- Outbound connections from the system to unknown external IPs
SIEM Query:
source="web_server" AND (uri_path="/admin" AND query_string="page=user*") AND (payload="*cmd*" OR payload="*shell*" OR payload="*exec*" OR payload="*system*")
