# 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

```python
# 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) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Reconnaissance** — Gather information about the target related to idor vulnerabilities. Identify attack surface.
2. **Vulnerability Identification** — Enumerate potential idor vulnerabilities weaknesses using automated and manual techniques.
3. **Exploit Development/Selection** — Choose or develop exploits targeting identified idor vulnerabilities vulnerabilities.
4. **Execution** — Execute the idor vulnerabilities test in a controlled manner with proper authorization.
5. **Post-Exploitation** — Document the impact and extent of successful exploitation.
6. **Reporting** — Write detailed findings with reproduction steps, impact assessment, and remediation guidance.

## Tools

- **Vulnerability Scanner** — Automated weakness identification
- **Exploitation Framework** — Controlled exploitation testing
- **Reporting Tool** — Findings documentation and tracking


## Process

1. **Reconnaissance** — Gather target information, identify attack surface, enumerate services
1. **Analysis/Exploitation** — Execute the technique, analyze results, document findings
1. **Reporting** — Document IOCs, write findings, provide remediation recommendations

## Verification

- [ ] All idor vulnerabilities procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
