PHPGurukul Small CRM SQL Injection Vulnerability in Profile.php

A SQL injection vulnerability has been identified in PHPGurukul Small CRM version 4.0, specifically within the profile.php file. This vulnerability arises from inadequate validation of user input in the 'name' parameter, allowing attackers to inject malicious SQL queries. The exploitation of this vulnerability could lead to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Notably, this vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries. This could result in unauthorized database access, data leakage, data modification or deletion, and potentially allow attackers to gain control over the system or disrupt its services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the profile.php file with the 'name' parameter crafted to include 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 implement input validation and use prepared statements to prevent SQL injection. Regular security audits can also help identify and address vulnerabilities.
