itsourcecode Online Voting System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the itsourcecode Online Voting System version 1.0. The issue arises in the file ajax.php, specifically within an unknown function that handles the action 'save_user'. The vulnerability allows remote attackers to manipulate the 'id' parameter, injecting malicious SQL code that could be executed by the database. This exploitation could lead to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows attackers to inject malicious SQL queries, potentially leading to unauthorized database access, manipulation or deletion of data, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/Voting/ajax.php?action=save_user' with a crafted 'id' 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

To address this vulnerability, 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 overall system security.
