TryHackMe OWASP Top10 Security Misconfiguration Walkthrough

The platform develops virtual classrooms that not only allow users to deploy training environments with the click of a button, but also reinforce learning by adding a question-answer approach. Its a comfortable experience to learn using pre-designed courses which include virtual machines (VM) hosted in the cloud.

TryHackMe OWASP Top-10 Security Misconfiguration Walkthrough


While using a question-answer model does make learning easier, TryHackMe allows users to create their own virtual classrooms to teach particular topics enabling them to become teachers. This not only provides other users with rich and varied content, but also helps creators reinforce their understanding of fundamental concepts.

Security Misconfiguration

Security Misconfigurations are distinct from the other Top 10 vulnerabilities, because they occur when security could have been configured properly but was not. TryHackMe OWASP Top10 Security Misconfiguration Walkthrough
Hack into the webapp, and find the flag!

Security misconfigurations include:


• Poorly configured permissions on cloud services, like S3 buckets

• Having unnecessary features enabled, like services, pages, accounts or
privileges

• Default accounts with unchanged passwords

• Error messages that are overly detailed and allow an attacker to find out more about the system

• Not using HTTP security headers, or revealing too much detail in the Server: HTTP header Task 20 Day 6



This vulnerability can often lead to more vulnerabilities, such as default credentials giving you access to sensitive data, XXE or command injection on admin pages.

 

Default Passwords

Specifically, this VM focusses on default passwords. These are a specific example of a security misconfiguration. You could, and should, change any default passwords but people often don't.


It's particularly common in embedded and Internet of Things devices, and much of the time the owners don't change these passwords.


It's easy to imagine the risk of default credentials from an attacker's point of view. Being able to gain access to admin dashboards, services designed for system administrators or manufacturers, or even network infrastructure could be incredibly useful in attacking a business. From data exposure to easy RCE, the effects of default credentials can be severe.


In October 2016, Dyn (a DNS provider) was taken offline by one of the most memorable DDoS attacks of the past 10 years. The flood of traffic came mostly from Internet of Things and networking devices like routers and modems, infected by the Mirai malware.


How did the malware take over the systems? Default passwords. The malware had a list of 63 username/password pairs, and attempted to log in to exposed telnet services.


The DDoS attack was notable because it took many large websites and services offline. Amazon, Twitter, Netflix, GitHub, Xbox Live, PlayStation Network, and many more services went offline for several hours in 3 waves of DDoS attacks on Dyn.

How to Solve ?

First of all, after deploying this room, you will get a IP Address, that IP Address has to be opened in the browser, where you will see the login page, you will have to enter the default username and password in that login page only then you will find the flag.



• Technique :- Google Dorking


• Then, open the new tab of browser and search :


site:github.com pensivenotes and hit enter.








• Open NinjaJc01 (James) · GitHub


• and scroll down and select & open a NinjaJc01/PensiveNotes





• Now, you have to open the file in README.md and after scrolling down you will get the default username and password.









• Login with this default username and password you will get the flag.
