Code-Projects Simple Blood Donor Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Code-Projects Simple Blood Donor Management System version 1.0. The issue resides in the '/simpleblooddonor/editeddonor.php' file, where the 'name' 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 potential leakage 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 manipulation, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the 'editeddonor.php' file with a crafted 'name' parameter that includes malicious SQL payloads. 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 enhance the application's security.
