itsourcecode Apartment Management System SQL Injection Vulnerability in Employee Salary Setup

A SQL injection vulnerability has been identified in the itsourcecode Apartment Management System version 1.0. The issue resides in the file '/setting/employee_salary_setup.php', where the 'MULTIPART ddlEmpName' parameter is not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and leakage of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's database queries. This could lead to unauthorized data access, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/setting/employee_salary_setup.php' with the 'ddlEmpName' parameter. Include a payload that exploits the SQL injection, such as one that uses a time-based blind SQL injection technique, like injecting a SQL query that causes a delay in the response time.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
