PHPGurukul Employee Record Management System SQL Injection Vulnerability in editmyexp.php

A critical SQL injection vulnerability has been identified in PHPGurukul Employee Record Management System version 1.3. The issue resides in the file editmyexp.php, specifically within the emp3workduration parameter. This vulnerability allows remote attackers to inject malicious SQL queries, which are executed without proper input validation or sanitization. As a result, attackers could manipulate SQL commands to access, modify, or delete database information.

Impact

Exploitation of this vulnerability could lead to unauthorized database access, allowing attackers to read, modify, or delete data. Additionally, it could result in the execution of administrative operations on the database, potentially compromising the entire application.

Reproduction

To reproduce this vulnerability, send a POST request to the editmyexp.php file with the emp3workduration parameter. Inject a payload that exploits the SQL injection vulnerability, such as one that uses boolean-based blind SQL injection techniques.

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, to prevent malicious input from being executed as part of an SQL command.
