ITSOURCECODE Electronic Judging System SQL Injection Vulnerability in Login.php

A SQL injection vulnerability has been identified in the ITSOURCECODE Electronic Judging System version 1.0, specifically in the login.php file. The issue arises from inadequate validation of the 'username' parameter, allowing remote attackers to inject malicious SQL queries. This vulnerability can be exploited without authentication, potentially leading to unauthorized database access, data manipulation, and leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with database queries. This could result in unauthorized data access, data modification or deletion, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a crafted request to 'intrams/login.php' with a payload that exploits the SQL injection flaw in the 'username' parameter. 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.
