Code-Projects Online Book Shop SQL Injection Vulnerability in process_login.php

A critical SQL injection vulnerability has been identified in Code-Projects Online Book Shop version 1.0. The issue arises in the file process_login.php, where the usernm parameter is processed without proper validation or sanitization, allowing attackers to manipulate the input and execute arbitrary SQL commands. This vulnerability can be exploited remotely, potentially leading to unauthorized access to the application's database or even remote code execution.

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. Additionally, according to a public proof of concept, this vulnerability could be exploited to gain remote code execution on the server.

Reproduction

To reproduce this vulnerability, send a POST request to the process_login.php file with a crafted usernm parameter that includes SQL injection payloads. The injected SQL code will be executed by the application's database, allowing for manipulation of the database or extraction of sensitive information.
