# Divulgation d’informations dans les messages d’erreur
### Divulgation d’informations dans les messages d’erreur
**Objectif du labo**
Ce laboratoire repose sur des \*\*messages d’erreur\*\* trop verbeux qui révèlent des informations sensibles sur l’application. / L’objectif est d’identifier et de soumettre la version d’un \*\*framework tiers vulnérable\*\* utilisé par le serveur.
**Observation initiale**
En manipulant le `productId` paramètre avec une valeur inexistante, par exemple :
```bash
/product?productId=ufeenu
```
L’application renvoie une **page d’erreur détaillée** au lieu d’un message générique.
**Informations divulguées**
Le message d’erreur expose explicitement des détails internes de l’application, notamment le framework utilisé et sa version exacte.
Dans ce cas, l’erreur révèle que l’application fonctionne avec :
```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/fr/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.
