itsourcecode E-Logbook with Health Monitoring System for COVID-19 SQL Injection Vulnerability

A SQL injection vulnerability has been identified in itsourcecode E-Logbook with Health Monitoring System for COVID-19 version 1.0. The issue resides in the login.php file, where the 'username' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely without authentication, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized access to the database, leakage of sensitive data, unauthorized data modification or deletion, and in some cases, execution of administrative operations on the database server.

Reproduction

The vulnerability can be reproduced by sending a POST request to the login.php file with a crafted 'username' 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 implement prepared statements and parameter binding to prevent SQL injection. Additionally, user input should be validated and filtered to ensure it meets expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance overall security.
