name	exploiting-api-injection-vulnerabilities
description	Use when tests APIs for injection vulnerabilities including SQL injection, NoSQL injection, OS command injection, LDAP injection, and Server-Side Request Forgery (SSRF) through API parameters, headers, and request bodies. The tester crafts malicious payloads targeting different backend technologies and injection contexts to extract data, execute commands, or access internal services. Maps to OWASP API8:2023 Security Misconfiguration and API7:2023 SSRF.

Exploiting Api Injection Vulnerabilities

Overview

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

When to Use

Trigger phrases:

• "exploiting api injection vulnerabilities"

• "Use when working with exploiting api injection vulnerabilities"

• Testing API endpoints that accept user input for database queries, system commands, or external requests

• Assessing APIs that interact with SQL databases, NoSQL stores (MongoDB, Redis), LDAP directories, or external URLs

• Evaluating input validation and parameterized query usage across all API endpoints

• Testing for SSRF where API parameters accept URLs or hostnames that trigger server-side requests

• Identifying injection points in headers, path parameters, query strings, and JSON/XML request bodies

Do not use without written authorization. Injection testing can modify or destroy data and compromise backend systems.

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

• Written authorization specifying target API and backend systems in scope
• Python 3.10+ with requests library
• SQLMap for automated SQL injection detection and exploitation
• Burp Suite Professional with Active Scan capabilities
• Knowledge of the backend database technology (MySQL, PostgreSQL, MongoDB, Redis)
• Isolated test environment to avoid production data corruption

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",
    : ,
}

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