# Divulgación de información en los mensajes de error
### Divulgación de información en mensajes de error
**Objetivo del laboratorio**
Este laboratorio se basa en mensajes de error demasiado detallados que revelan información sensible sobre la aplicación. / El objetivo es identificar y enviar la versión de un framework de terceros vulnerable utilizado por el servidor.
**Observación inicial**
Manipulando el `productId` parámetro con un valor inexistente, por ejemplo:
```bash
/product?productId=ufeenu
```
La aplicación devuelve una **página de error detallada** en lugar de un mensaje genérico.
**Información divulgada**
El mensaje de error expone explícitamente detalles internos de la aplicación, incluido el framework utilizado y su versión exacta.
En este caso, el error revela que la aplicación funciona con:
```bash
Apache Struts 2 2.3.31
```

## 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/information-disclosure/information-disclosure-in-error-messages.md?ask=&goal=
```
`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.
