Exploiting Type Juggling Vulnerabilities

Overview

Cybersecurity skill for exploiting type juggling vulnerabilities. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "exploiting type juggling vulnerabilities"

• "Exploit PHP type juggling vulnerabilities caused by loose comparison operators t"

• When testing PHP web applications for authentication bypass vulnerabilities

• During assessment of password comparison and hash verification logic

• When testing applications using loose comparison (== instead of ===)

• During code review of PHP applications handling JSON or deserialized input

• When evaluating input validation that relies on type-dependent comparison

When NOT to Use

• When you lack proper authorization for testing
• For production systems without change management
• When the task requires legal or compliance expertise beyond technical scope

Prerequisites

• Understanding of PHP type system and loose comparison behavior
• Knowledge of magic hash values (0e prefix) and their scientific notation interpretation
• Burp Suite for request manipulation and parameter type changing
• PHP development environment for testing payloads locally
• Collection of magic hash strings from PayloadsAllTheThings
• Ability to send JSON or serialized data to control input types

Legal Notice: This skill is for authorized security testing and educational purposes only. Unauthorized use against systems you do not own or have written permission to test is illegal and may violate computer fraud laws.

Workflow

# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs() -> :
     {k: re.findall(v, text)  k, v  IOC_PATTERNS.items()}
