# Injection SQL aveugle basée sur le temps

Notes sur l’injection SQL aveugle basée sur le temps pour les laboratoires PortSwigger Web Security Academy, y compris le flux de travail d’exploitation, les tests de charge utile, la validation avec Burp Suite et le contexte de remédiation.

### Injection SQL aveugle avec délais temporels

**Contexte :** la valeur du `TrackingId` le cookie est inséré dans une requête SQL exécutée **de manière synchrone**. La réponse HTTP n'indique pas directement le résultat de la requête, mais nous pouvons provoquer **un délai conditionnel** (sleep) pour déduire des informations (injection SQL aveugle basée sur le temps).

#### Charges utiles fournies (à placer après la partie légitime du cookie, par ex. `TrackingId=<BASE>' <CHARGE UTILE> -- -`)

* **MySQL** :

```
' AND SLEEP(10)-- -
```

* **PostgreSQL** :

```
' || pg_sleep(10)-- -
```

> Exemple concret (cookie) :/ `TrackingId=abc123' AND SLEEP(10)-- -` (MySQL)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/fr/web/sql-injection/time-based-blind-sql-injection.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
