HTB - Underpass
Underpass is an Easy Linux machine starting with a default Apache Ubuntu page. This leads the attacker to enumerate the machine with UDP ports for alternative attack vector, The attacker can enumerate SNMP and discover that Daloradius is running on the remote machine, and the operators panel can be accessed using the default credentials.
Relevant is a windows machine that has enabled smb which will going to exploit this services to access on the machine, and for the privilege escalation we are going to exploit windows access tokens.
Retro is a windows machine with wordpress site hosted on the port 80, which contain some credentials that allow access on the admin panel and get a reverse shell on the target machine, and lastly we escalete privileges abusing the CVE-2019-1388.
Alfred is a windows machine which has jenkins installed on the port 8080 and the first step is to exploit it and gain access to the machine, and in privilege escalation we are going to be exploiting the windows authentication tokens we are going exploit this in two ways, the first is using metasploit and then manually.
Steelmountain is windows machine inspired by the mr.robot serie, first we have a little osint challenge we need to indentify the person on the image on the website then we exploit the CVE-2014-6287 to gain access to the target machine and…

Ransom is Linux machine with a medium level defficulty both in exploitain, user own, privilage escalation phase, this involves vulnerabilities such as type juggling that helps us gain access to the web page, and we will also have an encrypted zip file that we must…
Solar is a linux machine with medium difficulty level in the exploitation phase and easy in privilege escalation, this machine runs the apache solr 8.11.0 service which is vulnerable to log4shell and also explains what is log4j, how it works, how to exploit log4shell step by step and ways to mitigate this vulnerability.
LogForge is a linux machine with a medium level of difficulty both in the exploitation phase and the privileges escalation, in this machine we take advantage of the vulnerability of the apache tomcat service to have access to the manager panel and we will also be exploiting a very critical vulnerability that has just been released recently which is the log4shell.
Horizontall is a linux machine with easy difficulty level both in the exploitation phase and the privilege escalation is cataloged as medium difficulty, this machine uses the cms strapi version 3.0 beta that has vulnerabilities such as RCE, change users passwords and also the machine has an http server running on port 8000 that is running laravel version 8 that has the vulnerability CVE-2021-3129 (RCE).
Secret is a linux machine with difficulty esay pulling in the exploitation phase when accessing the machine (which for me has not been easy, I will explaining this in this post) and the escalation of privileges is at medium level of difficulty, and this machine consists secret ways to extract information from applications, and this machine is vulnerable to RCE through an API.
Previse is a linux machine with difficulty esay pulling a little to medium both the level of intrusion and privilege escalation pulls a little to medium level of difficulty. this machine has vulnerabilities such as log poisoning and in the part of escalation we take advantage of nopasswd.
pikaboo is a machine with hard difficulty both at the level of instruction and escalation of privileges, It has vunlerabilities such as lfi on the web side and also perl vunlerability, as well as crendential access via ldap.
Backdoor is a linux machine with easy level both in explatation phase and PrivEs, in my opinion for me the explatation it’s medium level of difficulty…
We are going to learn how we can reverse shell in every OS, and some netcat commands that can help us when we are pentesting or scanning our environment.
we are going to learn how to scan a network or a host using nmap, we are going to see some simple nmap commands and commands that help us to pentest.
we are going to learn how to configure a dhcp server in linux using the isc-dhcp-server service, we are going to learn how to create subnets and make reserved ips.
We are going to learn how the app service works and the possibilities it offers us to manage the hosting since the app service is still a hosting but the difference is that we can manage it.
Tmux is a tool that allows us to divide a terminal in several panes and also to speed up when we are working in the console with different functions and shortcuts.
Rubber ducky by hak5 is a usb that simulates a keyboard that as soon as it is connected to a computer starts to write or perform the payload that we have indicated in a super fast way, in this article we will create some payloads and attacks that we can done and how to mitigate these types of attacks.
