A vulnerability was found in PHPGurukul Daily Expense Tracker 1.1 and classified as critical. Affected by this issue is some unknown functionality of the file /register.php. The manipulation of the argument email leads to sql injection. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.

Daily Expenses Management System version 1.0, developed by PHP Gurukul, contains a time-based blind SQL injection vulnerability in the 'add-expense.php' page. An attacker can exploit the 'item' parameter in a POST request to execute arbitrary SQL commands in the backend database. This can be done by injecting specially crafted SQL queries that make the database perform time-consuming operations, thereby confirming the presence of the SQL injection vulnerability based on the delay in the server's response.
