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 file '/admin/allemployees.php', where the 'delid' parameter can be manipulated to inject malicious SQL code. This exploitation occurs without proper input validation or sanitization, allowing attackers to interfere with SQL queries and execute unauthorized database operations. The vulnerability can be exploited remotely, posing significant risks to data integrity and system security.

Impact

Exploitation of this vulnerability allows attackers to inject malicious SQL queries, potentially leading to unauthorized database access, data manipulation or deletion, and execution of administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a GET request to '/admin/allemployees.php' with a crafted 'delid' parameter that includes SQL injection payloads. This can be done manually or using automated tools like sqlmap, which can exploit the vulnerability and extract database information.

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 restricting database user permissions.
