Code-Projects Online Medicine Guide SQL Injection Vulnerability in Change Password Functionality

A critical SQL injection vulnerability has been identified in the 'Online Medicine Guide' project, version 1.0. The issue resides in the '/changepass.php' file, where the 'ups' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and access to sensitive information. Such actions pose a significant threat to system security and data integrity.

Reproduction

The vulnerability can be reproduced by sending a POST request to the '/changepass.php' file with the 'ups' parameter. Various payloads can be used to exploit the SQL injection, such as boolean-based blind injection or error-based injection, taking advantage of the application's SQL query handling.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
