Description
The web shop application „Gambio GX“ contains a blind SQL injection vulnerability in the admin area. The vulnerability allows an authenticated attacker with administrative privileges to leak database contents.
Introduction
The application gambio has a blind SQL injection vulnerability in the admin area. The file /admin/mobile.php between line 75 and 94 contains the vulnerable code. The POST argument $order_id is passed to the application and is concatenated with the SQL query. An attacker could exploit this to manipulate the database query.
