FirstBlood-#824 — Administrator endpoints can be accessed by non privileged doctor accounts which reveals sensitive patient information.
This issue was discovered on FirstBlood v2.0.0 (issues patched)
On 2021-10-29, vishal Level 2 reported:
Discription :Administrator endpoints can be accessed by non privileged doctor accounts which reveals sensitive patient information.
Steps to Reproduce:
I have foudnt that admin can query for patient using endpoint /drpanel/drapi/qp.php by name parameter in body . However in web UI new doctor's who are not admin aren't allowed to search for patient by name but new doctor's can still use admin endpoint and use their cookie drps to access detail's of patient.
Capture the Request when you query for patient as admin and send it to repeater . request should look like below one.
Now Relogin as a new a new non-admin doctor and change your drps cookie with the account of new doctor. you will still be able to access the user's detail's as below.
Impact: New Doctor's are not supposed to access private information about of patient but using admin end point they are able to query about patient. Which is only supposed to accessed from old or admin doctor's.
Lastly if I Missed something or further details required just let me know - Vishal

The endpoint qp.php use to respond to GET requests and it should only allow administrators to query for patient information however the developers only fixed the bug partially and it still allowed for doctors to query for patient information. query.php is related to this file and in v1 allowed for Doctors and admins, but query.php was fixed completely whereas qp.php was not.
