PHPGurukul Local Services Search Engine Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Local Services Search Engine Management System version 2.1. The issue resides in the file '/admin/changeimage.php', where the 'editid' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized access to the database, data modification or deletion, and leakage of sensitive information.

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 execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/admin/changeimage.php' with the 'editid' parameter. The request should include a payload that exploits the SQL injection vulnerability, such as a boolean-based blind injection or a UNION-based injection. This can be done using a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to update the application to a version that addresses this vulnerability. If no such version is available, consider applying general SQL injection mitigation techniques, such as using prepared statements and parameterized queries, validating and sanitizing user inputs, and minimizing database user privileges.
