# Devzat - 8443

Abus du paramètre fichier Devzat, découverte de sauvegarde, traversal de chemin, lecture du fichier shadow et accès à la clé SSH root.

### Port 8443 (Devzat - production)

Le port 8443 expose une instance Devzat en production. Le `fichier` paramètre peut lister les fichiers du système en tant que root, mais cette fonctionnalité est protégée par mot de passe.

### Recherchez les fichiers lisibles par Catherine

Trouvez tous les fichiers lisibles par *catherine*:

```bash
find / -user catherine -readable 2>/dev/null | grep -vE "cgroup|proc"
```

Deux sauvegardes `.zip` fichiers sont trouvés :

* `/var/backups/devzat-main.zip`
* `/var/backups/devzat-dev.zip`

Téléchargez le fichier de sauvegarde `devzat-dev.zip` et filtrez son contenu à la recherche de mots de passe. Un mot de passe utile est trouvé : **`CeilingCatStillAThingIn2021?`**.

Utilisez ce mot de passe pour accéder à `/etc/shadow` via le `fichier` :

```bash
/file /etc/shadows CeilingCatStillAThingIn2021?
```

Bien que le mot de passe soit correct, **le path traversal** est nécessaire pour obtenir un accès complet. Utilisez la traversée pour naviguer dans le système de fichiers :

```bash
/file ../../../../etc/shadow CeilingCatStillAThingIn2021?
```

Le `/etc/shadow` le fichier s'affiche correctement en tant que root.

### Accès SSH en tant que root

Utilisez une traversée de chemin supplémentaire pour accéder à la clé SSH de root :

```bash
/file ../../../../root/.ssh/id_rsa CeilingCatStillAThingIn2021?
```

Téléchargez la clé SSH et connectez-vous en tant que root.

# 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/devzat-8443.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.
