PHPGurukul Hospital Management System SQL Injection Vulnerability in Version 4.0

A SQL injection vulnerability has been identified in PHPGurukul Hospital Management System version 4.0. The issue resides in the file '/admin/doctor-specilization.php', where the 'doctorspecilization' parameter is manipulated, leading to unauthorized database access. This vulnerability can be exploited remotely, without any authentication, allowing attackers to inject malicious SQL queries, access and modify sensitive data, and potentially disrupt database operations.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/doctor-specilization.php' with the 'doctorspecilization' parameter. The request should include a payload that exploits the SQL injection vulnerability, such as a time-based blind SQL injection payload that uses a SQL injection technique to extract information from the database by making the database wait for a specified amount of time before responding.

Remediation

It is recommended to validate and sanitize user inputs, use prepared statements to prevent SQL injection, and minimize database user permissions.
