PHPGurukul Complaint Management System SQL Injection Vulnerability in Admin Profile Management

A critical SQL injection vulnerability has been identified in PHPGurukul Complaint Management System version 2.0. The issue resides in the admin profile management file, specifically within the 'mobilenumber' parameter. This vulnerability allows remote attackers to inject malicious SQL queries, which could be executed without authorization, potentially leading to unauthorized database access, data manipulation, and disclosure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can interfere with the application's 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/admin-profile.php' with a crafted 'mobilenumber' 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

It is recommended to validate and sanitize user inputs, particularly for parameters that are used in SQL queries. Implementing prepared statements and parameterized queries can also help prevent SQL injection attacks.
