PHPGurukul COVID19 Testing Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul's COVID19 Testing Management System version 1.0. The issue resides in the '/password-recovery.php' file, where the 'contactno' parameter is manipulated to inject malicious SQL queries. This vulnerability allows remote attackers to access the database, leak sensitive information, alter or delete data, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows unauthorized database access, manipulation of database contents, and interception of sensitive information, posing a significant risk to system integrity and availability.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'password-recovery.php' with crafted payloads that exploit the SQL injection flaw in the 'contactno' 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, validate and filter user input, minimize database user permissions, and conduct regular security audits.
