Code-Projects Modern Bag SQL Injection Vulnerability in action.php

A critical SQL injection vulnerability has been identified in the Code-Projects Modern Bag version 1.0, specifically within the action.php file. The issue arises from inadequate validation of user input in the proId 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 POST request to action.php with the proId parameter. The injected SQL payload can be crafted to exploit the application's SQL query handling, such as using boolean-based blind injection techniques or error-based injection to extract database information.

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.
