🚨 pgAdmin 4 Meta-Command Filter Bypass — RCE

📌 Vulnerability Summary
➕ Product: pgAdmin 4
➕Affected Versions: ≤ 9.10
➕Fixed Version: 9.11
➕Impact: Remote Code Execution (RCE) on pgAdmin host

Attackers can craft a malicious PLAIN-format SQL dump that bypasses pgAdmin’s meta-command filter, resulting in command execution on the server when a restore operation is performed.

🖥 Day 29 – Linux Memory Analysis & Credential Hunting

Secrets often live only in memory, not on disk. If you can read process memory, encryption and file permissions often don’t matter.

🟡 Quick checks:

ls /proc
ls /proc/<pid>
cat /proc/<pid>/environ | tr '\0' '\n'
ps aux | grep -i pass

High-value targets:
➕Running services (DBs, web servers)
SSH agents
➕Root-owned daemons
➕Apps loading secrets via env vars

🟡 Memory hunting basics:

strings /proc/<pid>/mem | grep -i pass
cat /proc/<pid>/maps

- If ptrace is allowed, attaching to live processes can reveal passwords, tokens, and decrypted configs.

🎓Understanding PII and Initial Discovery Techniques (Part 1/3)🎓

Personally Identifiable Information (PII) is any data that can identify an individual. In security testing and bug bounty hunting, finding exposed PII is a critical high-impact discovery. This series will cover discovery, validation, and reporting across three parts.

🔥 What Actually Qualifies as PII?

🔸 Direct Identifiers (Highest Risk): National ID (SSN), Passport Number, Full Name + Date of Birth, Driver's License Number
🔸 Digital Identifiers: Email Address, IP Address, Account Username, Device ID, Social Media Profile with identifying details
🔸 Financial Identifiers: Full Credit/Debit Card Number (PAN), Bank Account Number
🔸 Contextual Identifiers: Information that, when combined (e.g., Job Title + Company + City), can identify a person.

💡 Why PII Hunting is Critical for Security & Bounty

▫️ Legal & Compliance: Exposing PII violates major regulations like GDPR, CCPA, and HIPAA, leading to massive fines.
▫️ High-Impact Findings: A single leak can affect thousands of users, making it a high-severity bug bounty issue.
▫️ Real-World Harm: Exposed data fuels identity theft, financial fraud, and phishing attacks.

🛠 Part 1: The Reconnaissance & Initial Discovery Phase
- The goal is to find data entry points and potential leak sources.

1. Target Surface Mapping:
➕ Map all subdomains: assetfinder, subfinder, amass
➕ Identify technologies: wappalyzer, builtwith
➕ Find parameters: arjun, paramspider

2. Google Dorking for Obvious Leaks:

site:example.com filetype:csv | filetype:xlsx | filetype:pdf
site:example.com "confidential" | "internal" | "employee list"
intitle:"index of" "backup" site:example.com

3. Basic Fuzzing for Common Files:

# Look for common backup/config files containing data
ffuf -w ~/SecLists/Discovery/Web-Content/common.txt -u https://target.com/FUZZ -e .bak,.old,.txt,.sql,.tar.gz

⚡️Other important tools : subfinder, amass, httpx, gobuster .

⚠️ Pro Tip: Always check /robots.txt and /.git/ for clues about hidden directories containing data!

🎓 Deep-Dive PII Hunting & Validation Techniques ( Part 2/3 )

Now that you've mapped the target, it's time to hunt for the data itself. This part focuses on advanced discovery, pattern matching, and validating what you've found.

🔥 Where PII Hides: Common Sources of Exposure

➕ Insecure APIs: Undocumented or poorly secured endpoints like /api/v1/users, /admin/profile

➕ Misconfigured Cloud Storage: Publicly accessible Amazon S3 buckets, Azure Blobs, or Google Cloud Storage

➕ Application Debug Files: Log files (debug.log), configuration dumps (config.json), and error messages revealing queries with user data.

➕ Client-Side Storage: PII accidentally embedded in JavaScript files, HTML comments, or local storage.

🎓 XSS WAF Bypass: 3 Tricks to Beat Alert Blockers 🎓

Modern WAFs often block the word “alert” in XSS payloads, but JavaScript’s flexibility lets you reconstruct it dynamically. Here are three powerful obfuscation techniques that bypass keyword-based filters by breaking, encoding, or dynamically generating the alert function.

⚡️ Why These Bypass WAF Filter
🔸 No Direct “alert” String: The word is split, encoded, or constructed dynamically
🔸 JavaScript Weirdness: Uses obscure language features WAF regex doesn’t anticipate
🔸 Context Evasion: Template literals, regex properties, and Unicode aren’t in standard XSS signatures
🔸 Multi-Stage Execution: WAF sees fragments, browser executes final result

🖥 Day 30 – Building Your Linux Hacking Workflow (FINAL DAY)
Real operators don’t just know commands — they build repeatable workflows for recon, exploitation, logging, monitoring, and reporting.

Quick setup:

mkdir -p ~/targets/{logs,loot,scans,exploits}
alias ports='ss -tulnp'
nmap -sC -sV target | tee -a scans/nmap.txt

Core workflow:
Recon → Enumeration → Exploitation
PrivEsc → Persistence → Logging → Cleanup

Essential daily checks:

ip a
sudo -l
find / -perm -4000 2>/dev/null
tail -f /var/log/auth.log

Best operators:
- automate repetitive work
- document everything
- monitor constantly
- think like both attacker & defender
