Sensitive Data Exposure or Password Disclosure in H1C Private site



Hello Friends,

Recently, I found a critical bug in private site which discloses all sensitive data or information of users.





The bug exist in forgot password page. I just enter my email in forgot password page and try to reset the password and the site discloses all information of my account in response.While resetting, I just Intercept the request through Burp and send to repeater and change my email to any registered user email and click on 'Go'. In response, site discloses user sensitive information like phone number etc. along with a password in Sha256 hash.
After decrypting the hash, hacker gets the password.
Also, we don't need to decrypt the password hash we can directly use password hash by modifying the requests. 

 



Conclusion:

Always check forgot password page or forgot password functionality for vulnerabilities. You'll get the idea.

  
Thanks for reading.

Hello Friends, I'm gonna share my interesting finding here. Recently,  About two months ago,  I received a private invitation on Bugcrowd and the next day I started to look for bugs on that website because there was only one target (testing site) in scope and they provided me some credentials. I can't disclose the site name, so let's assume https://redacted.com First of all, I logged-in to that site (redacted.com) with the provided credentials and inspected the site around 15 minutes and tried to understand it. After that, I started to look for bugs and found multiple bugs mostly stored XSS. At that day, I had found a total 11 vulnerabilities. I reported them and received a bounty on each report. So, I'm not disclosing the bounties. Also, I'm not sharing my all findings but some. So,  At the beginning, I tried to change my default password and successfully changed my password to '1' which was the first bug that there is no password policy.
