# Elasticsearch - 9200

Énumération des index Elasticsearch, revue de l’exposition des données, filtrage par mots-clés et récupération d’identifiants encodés en base64.

{% hint style="info" %}
Elasticsearch est un moteur de recherche et d’analyse en temps réel utilisé pour indexer et rechercher rapidement de grands volumes de données. Il s’intègre à la stack ELK pour fournir des capacités avancées de visualisation et d’analyse des données.

En accédant au `/_cat/indices?` L’URL renvoie une liste d’indices avec leurs UUID. Pour extraire le contenu d’un index, utilisez l’URL suivante :

`http://haystack.htb:9200/<index>/_search?pretty=true&size=1000`

**Filtrage des données avec Curl**

En utilisant les `citations` en filtrant l’index et le mot-clé du défi, des informations pertinentes sont trouvées :

```bash
curl -s -X GET "http://haystack.htb:9200/quotes/_search?pretty=true&size=1000" | jq | grep -Ei "clave"
```

**Décodage de chaînes encodées en Base64**

Deux chaînes encodées en base64 sont récupérées. Leur décodage révèle les identifiants :

```bash
echo -n "cGFzczogc3BhbmlzaC5pcy5rZXk=" | base64 -d; echo
echo -n "dXNlcjogc2VjdXJpdHkg" | base64 -d; echo
```

# 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/ports-and-services/elasticsearch-9200.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.
