FirstBlood-#1543Anyone can edit doctors
This issue was discovered on FirstBlood v3

On 2022-12-11, pichik Level 4 reported:



After creating custom wordlist I found another hidden endpoint /api/managedoctors.php.
This endpoint allows anyone to edit doctors.
As POST gives us Unauthorised!, we can just use PUT request, which works fine.
By working step by step on this request, response will reveal to us everything what we need - that we need to send json and all params requried.

Here is simple request:

PUT /api/managedoctors.php HTTP/1.1
Content-Length: 88

"bio":"Hello there",



Attacker can mess with doctors reputation, or combine it with XSS to attack users as well.


Be more careful with managing/removing public endpoints, as they still be fuzzed accessed if no server side prevention is added.
This endpoint should be made just internal only.
