# Injection SQL dans la clause WHERE

### Vulnérabilité d’injection SQL dans la clause WHERE permettant la récupération de données cachées

* **Contexte / Vulnérabilité :** Le filtre de catégorie est vulnérable à une injection SQL. La requête typique exécutée sur le serveur :/ `SELECT * FROM products WHERE category = 'Gifts' AND released = 1`
* \*\*Objectif de l’attaque (lab) :\*\* forcer l’affichage d’un ou plusieurs produits non publiés (`released = 0`).
* **Paramètre vulnérable :** `category` (filtre de produits).
* **Preuve de concept (payload fourni) :**

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

* Interprétation rapide : le payload modifie la condition WHERE pour inclure les entrées où `category='Lifestyle' AND released=0`, en contournant la `released = 1` contrainte.
* **Résultat attendu :** la page renvoie et affiche les produits correspondant à `released = 0` (produits non publiés).
* **Impact :** divulgation d’éléments masqués, exfiltration potentielle de données sensibles, contournement de la logique métier (non destinée au public).

## 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/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.
