PHPGurukul Emergency Ambulance Hiring Portal SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Emergency Ambulance Hiring Portal version 1.0. The issue resides in the file '/admin/contact-us.php', where the 'mobnum' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to access and manipulate the database without authorization.

Impact

Exploitation of this vulnerability could lead to unauthorized database access, allowing attackers to read, modify, or delete data. Additionally, it could result in the execution of administrative operations on the database, potentially leading to a complete compromise of the application.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/eahp/admin/contact-us.php' with the 'mobnum' parameter. The injected SQL payload can be crafted to exploit the application's database query handling. For example, a time-based blind SQL injection payload could be used, where the injection is confirmed by the application's response time.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to separate SQL code from user input. Additionally, input validation and filtering should be applied to ensure that data conforms to expected formats, preventing malicious input from being processed. Finally, database user permissions should be minimized, ensuring that the account used for database connections has only the necessary privileges.
