Code-Projects Online Product Reservation System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Code-Projects Online Product Reservation System version 1.0. The issue arises in the file 'app/products/left_cart.php', where user input from the POST parameter 'id' and the session variable 'id' are directly concatenated into SQL queries without proper validation. This vulnerability allows remote attackers to manipulate cart contents and potentially extract sensitive data from the database.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, or in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a crafted POST request to 'app/products/left_cart.php' with an 'id' parameter that includes SQL injection payloads. The absence of input validation allows the injected SQL code to be executed, manipulating the application's database queries and cart functionality.
