Projectworlds Advanced Library Management System SQL Injection Vulnerability in borrow_book.php

A SQL injection vulnerability has been identified in Projectworlds Advanced Library Management System version 1.0, specifically within the borrow_book.php file. The issue arises from inadequate validation of the roll_number parameter, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to borrow_book.php with a payload that exploits the SQL injection flaw in the roll_number parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
