# Inyección SQL en la cláusula WHERE

### Vulnerabilidad de inyección SQL en la cláusula WHERE que permite recuperar datos ocultos

* **Antecedentes / Vulnerabilidad:** Filtro de categoría vulnerable a inyección SQL. La solicitud típica ejecutada en el servidor:/ `SELECT * FROM products WHERE category = 'Gifts' AND released = 1`
* \*\*Objetivo del ataque (laboratorio):\*\* forzar la visualización de uno o más productos no publicados (`released = 0`).
* **Parámetro vulnerable:** `category` (filtro de productos).
* **Prueba de concepto (carga útil proporcionada):**

```sql
test' or category='Lifestyle' and released=0-- -
```

* Interpretación breve: la carga útil modifica la condición WHERE para incluir entradas donde `category='Lifestyle' AND released=0`, eludiendo la `released = 1` restricción.
* **Resultado esperado:** la página devuelve y muestra productos correspondientes a `released = 0` (productos no publicados).
* **Impacto:** divulgación de elementos ocultos, posible exfiltración de datos sensibles, elusión de la lógica de negocio (no destinada al público).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/es/web/sql-injection/sql-injection-in-where-clause.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
