A critical vulnerability has been discovered in the SourceCodester Inventory Management System 1., which allows for a possible SQL injection attack. The vulnerability is present in the file app/ajax/search_sell_paymen_report.php where an unknown function is affected due to the manipulation of the 'customer' argument. Attackers can exploit this vulnerability remotely, and the exploit has now been made public, raising the risk of potential cyber attacks for users of this system.

Vulnerability Details

The critical vulnerability has been assigned the identifier VDB-237558 and is found in the SourceCodester Inventory Management System 1.'s file app/ajax/search_sell_paymen_report.php. By manipulating the 'customer' argument in this file, it is possible to launch a SQL injection attack, thereby giving the attacker the possibility to access, modify or delete sensitive data hosted in the application's database.

The following code snippet demonstrates the vulnerability in action

<?php
...
$sql = "SELECT ... FROM ... WHERE customer = '$customer' ... ";
$result = $conn->query($sql);
...
?>

In the above code snippet, the 'customer' variable is not sanitized or validated before being used in the SQL query. This allows attackers to manipulate the 'customer' argument with malicious SQL code, leading to an SQL injection.
