Hello Zseano! I found a business logic error on
/drpanel/drapi/query.phpand as a normal doctor, I was able to read any patient's personal data. Normally, this should not be possible for new doctors
Steps to reproduce
- Create a new account on
- Next, navigate to
/drpanel/drapi/query.php?aptid=56911019. The ID can be obtained by either logging in as an administrator or by bruteforcing the value. The first 4 digits look to be static and do not change, so only the last 4 can or need to be bruteforced.
- After the page loaded, we can easily read the personal date of Mrs Melissa White.

Thanks a lot for the fun challenge! Have a nice day!
