# Elasticsearch - 9200
Elasticsearch-Index-Enumeration, Prüfung von Datenoffenlegung, Keyword-Filterung und Wiederherstellung von Base64-Credentials.
{% hint style="info" %}
Elasticsearch ist eine Such- und Analyse-Engine in Echtzeit, die verwendet wird, um große Datenmengen schnell zu indizieren und zu durchsuchen. Sie integriert sich in den ELK-Stack, um erweiterte Funktionen zur Datenvisualisierung und -analyse bereitzustellen.
{% endhint %}
### Elasticsearch - Informationsleck
#### Auf Port 9200 wird Elasticsearch Version 6.4.2 gehostet.
Beim Zugriff auf das `/_cat/indices?` Die URL gibt eine Liste der Indizes mit ihren UUIDs zurück. Um den Inhalt eines Index zu extrahieren, verwenden Sie die folgende URL:
`http://haystack.htb:9200//_search?pretty=true&size=1000`
**Datenfilterung mit Curl**
Unter Verwendung der `Zitate` und beim Filtern des Challenge-Schlüsselworts im Index werden relevante Informationen gefunden:
```bash
curl -s -X GET "http://haystack.htb:9200/quotes/_search?pretty=true&size=1000" | jq | grep -Ei "clave"
```
**Decodieren von Base64-kodierten Zeichenfolgen**
Zwei Base64-kodierte Zeichenfolgen werden wiederhergestellt. Durch das Decodieren werden die Anmeldedaten offengelegt:
```bash
echo -n "cGFzczogc3BhbmlzaC5pcy5rZXk=" | base64 -d; echo
echo -n "dXNlcjogc2VjdXJpdHkg" | base64 -d; echo
```

# Agent Instructions

## 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/de/ports-and-services/elasticsearch-9200.md?ask=&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.
