Code-Projects Automated Voting System SQL Injection Vulnerability in Update User Script

A SQL injection vulnerability has been identified in Code-Projects Automated Voting System version 1.0. The issue resides in the '/admin/update_user.php' file, where the 'password' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with database queries. This could result in unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/admin/update_user.php' with a crafted 'password' parameter that includes SQL injection payloads. The injection can be time-based, using SQL functions like SLEEP to demonstrate the vulnerability.

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.
