In this walk through, we will be going through the HTML Injection (User Lookup Xpath) vulnerability section from Mutillidae Labs. We will be exploring and exploiting HTML Injection in User Lookup Xpath and learn how application are affected because of it. So, let’s get started with the Hacking without any delay.
Table of Contents
Security Level: 0 (Hosed)
- Setting the security level to 0 or Hosed.
- The application has a user lookup functionality which requires a pair of credentials to view the user’s information.
- I used the below payload in both username and password field to dump all the users information.
' or '1'='1

Conclusion:
So, we finally completed all the security levels for the HTML Injection (User Lookup Xpath) 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 potential HTML Injection attacks by performing input sanitization on endpoints, whitelist the allowed characters in the input and using a WAF. Along with that, we can prevent data from any untrusted source to be dynamically written to the HTML document. On that note, i will take your leave and will meet you in next one with another Mutillidae vulnerability writeup, till then “Keep Hacking”.
