Code-Projects Online Medicine Guide SQL Injection Vulnerability in Login.php

A critical SQL injection vulnerability has been identified in the 'Online Medicine Guide' project, version 1.0. The issue resides in the '/login.php' file, where insufficient validation of the 'uname' parameter allows 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, enabling attackers to interfere with the application's database queries. This could lead to unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'login.php' with an injected payload in the 'uname' parameter. This payload can be crafted to exploit the SQL injection, such as by using error-based or time-based blind injection techniques. The injection takes advantage of the application's SQL query handling, allowing the attacker to manipulate database operations.

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.
