PHPGurukul Employee Record Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Employee Record Management System version 1.3. The issue resides in the 'editmyeducation.php' file, where the 'coursepg' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication or authorization.

Impact

Exploitation of this vulnerability allows attackers to gain unauthorized access to the application's database, potentially leading to data manipulation, unauthorized data access, and in some cases, full system control.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'editmyeducation.php' with the 'coursepg' parameter. The request should include a crafted SQL injection payload that exploits the application's SQL query handling. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to implement prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, ensuring that the database account used by the application has only the necessary privileges.
