SourceCodester Pharmacy Sales and Inventory System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester Pharmacy Sales and Inventory System version 1.0. The issue arises in the file '/ajax.php?action=delete_receiving', where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions pose a significant threat to the system's security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/ajax.php?action=delete_receiving' with a crafted 'id' parameter that includes malicious SQL code. This injection takes advantage of the application's failure to properly validate or sanitize user input, allowing the injected SQL to be executed by the database.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
