Mutillidae - Sensitive Data Exposure

Mutillidae – Sensitive Data Exposure

In this walk through, we will be going through the Sensitive Data Exposure vulnerability section from Mutillidae Labs. We will be exploring and exploiting Sensitive Data Exposure in various implementations and learn how application are affected because of it. So, let’s get started with the Hacking without any delay.

Sensitive Data Exposure

Security Level: 0 (Hosed)

  • Setting the security level to 0 or Hosed.

Security level 0

  • Using gobuster to reveal sensitive directories by bruteforcing.

gobuster dir -u http://localhost/mutillidae/ -w ~/Desktop/Wordlist/common.txt 

gobuster scan

So, we finally completed all the security levels for the Mutillidae Sensitive Data Exposure Vulnerability. We looked into the various ways how application has been set up in various levels and how we can bypass the security controls implemented. Next, we can mitigate the Sensitive Data Exposure attacks by cataloging sensitive data and performing risk assessment. Along with that, appropriate security controls in place to avoid the occurrence of sensitive data exposures as well as to limit their impacts on data subjects. On that note, i will take your leave and will meet you in next one with another Mutillidae vulnerability writeup, till then “Keep Hacking”.
