This guide walks through a real-world PostgreSQL penetration testing workflow from reconnaissance to post-exploitation, demonstrating scanning, authentication attacks, file reads, command execution, and reverse shells using practical examples. It also outlines Metasploit and client-based techniques, credential attacks, and actionable hardening and remediation steps to secure PostgreSQL deployments. #PostgreSQL #Metasploit
Keypoints
- PostgreSQL is a high-value target and testing covers reconnaissance, scanning, and service discovery.
- Lab setup includes installing PostgreSQL, creating users/databases, and configuring remote access for testing.
- Common attacks include credential-based brute forcing, file reading via pg_read_file, and password hash dumping with Metasploit.
- Command execution techniques (COPY FROM PROGRAM) enable system command execution and reverse shells, often escalated to Meterpreter.
- Effective remediation requires strong passwords, least-privilege roles, logging/monitoring, patch management, and configuration hardening.
