Exploiting Idor Vulnerabilities

Overview

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

When to Use

Trigger phrases:

• "exploiting idor vulnerabilities"

• "Identifying and exploiting Insecure Direct Object Reference vulnerabilities to a"

• During authorized penetration tests when testing access control on resource endpoints

• When APIs or web pages use predictable identifiers (numeric IDs, UUIDs, slugs) in URLs or request bodies

• For validating that object-level authorization is enforced across all CRUD operations

• When testing multi-tenant applications where users should only access their own data

• During bug bounty programs targeting broken access control vulnerabilities

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

• Authorization: Written penetration testing agreement for the target application
• Burp Suite Professional: With Authorize extension installed from BApp Store
• Two test accounts: At least two separate user accounts with different permission levels
• Burp Authorize Extension: For automated IDOR testing across sessions
• curl/httpie: For manual request crafting
• Browser: Configured to proxy through Burp Suite

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