How 2 Cute Bugs offered me a reward of 650€
Hey amazing cyberfolks 😊 !!. This is me ani ! back with an interesting vulnerabilities I found ,for which I was awarded a bounty of 650€.
Okay now lets started !!!. That was a fine weekend saturday, I was lazy af and bored🥱 , I decided to start hunting to kick off my laziness😎 . I usually hunt on private programs i discover from google dorks since hackerone and bugcrowd is “crowded” sometimes. I don’t recommend you either to always hunt on these random dork programs as you may be disappointed with unresponsiveness many times :(
Anyways I went to this Github repo where it contains curated list of google dorks to discover program which offer responsible disclosure programs. I randomly picked one dork.
responsible disclosure bounty r=h:eu
I decided to choose an very old program so I traversed many pages and picked on random domain. Lets call it “redacted.com“. “redacted.com” was an online travel goods purchasing e commerce site. It had various functionalities , I registered an account and started to play around. I tested for login issues and authentication related bugs but unfortunately no luck :(
There was a search feature , i searched for testbro and I noticed my input was reflected in the webpage. I decided to break the “” and inject an XSS payload (like “<img src=xss onerror=alert(1)>) and when I hit search to my surprise payload got executed and I saw an pop 🤩.
I noticed an important thing whenever we click on any project the product ID was with an numerical number in the url like “redacted.com/products?productID=21”. Any idea struck on my mind why don’t we try for Sql Injection and decided to put an ‘ after like productId=21’. To my surprise i got an sql syntax error back from the server like the below
I was like WHATTTTT!!. Since I am an lazy ass hunter I decided to exploit this using SQLMAP tool (but I highly recommend trying out payload manually to understanding) . Okayy now back with the hunting.
I used the below command to dump all the databases present in the target:
sqlmap -u http://redacted.com/products?productID=21 --dbs
It dumped all the databases , next I several databases one of them caught my eye. I used that database name and dumped all the tables present using the below command:
sqlmap -u http://redacted.com/products?productID=21 -D redacted --tables
It dumped all the tables, one of them caught my eye , it named “users”. I decided to dump that tables . I used the below command for that:
sqlmap -u http://redacted.com/products?productID=21 -D redacted -T users --dump-all
Wow, it dumped all the details and WHATT admin username and password were also among them
I got the admin username and password was of some sort of encoding. I used cyberchef.io and figured out it was base64 and decoded it and got the password :)
Okay now that I have username and password. I need to find a way to login as admin. I decided to do directory brute force using gobuster tool , i got an endpoint like “redacted.com/admin/login”. So now you guys might have guessed what I must have done. I used those credentials and logged in as admin , YEA !!!
Now I made an detailed reported regarding the findings and submitted to redacted.com security team. After 3 days , they decided to offer me a reward of 650€ for report.
