## What it does

The skill guides security testers through an assessment process for SQL injection vulnerabilities. It covers mapping parameters in GET, POST, headers, and API payloads, identifying database engines like MySQL, PostgreSQL, MSSQL, or Oracle, and testing parameters through union or blind methods. It also structures validation workflows with sqlmap.

Running this skill requires written authorization, Burp Suite Professional, an up-to-date sqlmap installation, and dedicated test accounts. Executing these tests on live production databases without explicit scope approval is prohibited because it threatens database integrity.

## Requirements
- Works with: PostgreSQL

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill exploiting-sql-injection-vulnerabilities -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/exploiting-sql-injection-vulnerabilities/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/exploiting-sql-injection-vulnerabilities/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill exploiting-sql-injection-vulnerabilities -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/exploiting-sql-injection-vulnerabilities/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill exploiting-sql-injection-vulnerabilities -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/exploiting-sql-injection-vulnerabilities/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mukul975/Anthropic-Cybersecurity-Skills exploiting-sql-injection-vulnerabilities
```

2. **Manually: put the files in place**
- File: `.github/skills/exploiting-sql-injection-vulnerabilities/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill exploiting-sql-injection-vulnerabilities -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mukul975/Anthropic-Cybersecurity-Skills --path skills/exploiting-sql-injection-vulnerabilities
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/exploiting-sql-injection-vulnerabilities/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mukul975/Anthropic-Cybersecurity-Skills --skill exploiting-sql-injection-vulnerabilities -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mukul975/Anthropic-Cybersecurity-Skills/tree/HEAD/skills/exploiting-sql-injection-vulnerabilities/SKILL.md

## When to use it
- map input parameters across headers, URLs, and JSON payloads
- fingerprint database engines and versions from server responses
- verify parameterized query implementations and input filters
- test web application firewall resilience against injection inputs

## Example prompts
- Outline an assessment workflow to test web application parameters for SQL injection flaws
- Identify the database engine based on syntax errors observed in test responses
- Format sqlmap commands to test a login parameter with our test credentials

# Exploiting SQL Injection Vulnerabilities

## When to Use

- Testing web application input parameters for SQL injection vulnerabilities during an authorized penetration test
- Validating that parameterized queries and input sanitization are properly implemented across all database interactions
- Demonstrating the business impact of a confirmed SQL injection vulnerability by extracting sensitive data
- Verifying that WAF rules and input validation controls effectively block SQL injection payloads
- Testing stored procedures, dynamic SQL, and ORM bypass scenarios in enterprise applications

**Do not use** against databases without written authorization, for extracting or exfiltrating actual customer data beyond what is needed for proof of concept, or against production databases where exploitation could corrupt data integrity.

## Prerequisites

- Written authorization specifying the target application and permissible level of exploitation (detection only vs. full exploitation)
- Burp Suite Professional configured as an intercepting proxy to capture and modify HTTP requests
- sqlmap installed with current version for automated detection and exploitation
- Knowledge of the target database engine (MySQL, PostgreSQL, MSSQL, Oracle) or ability to fingerprint it
- Test accounts at various privilege levels to test injection in authenticated contexts

## Workflow

### Step 1: Injection Point Discovery
