itsourcecode Apartment Management System SQL Injection Vulnerability in Maintenance Cost Management

A SQL injection vulnerability has been identified in the itsourcecode Apartment Management System version 1.0. The issue arises in the file '/maintenance/add_maintenance_cost.php', where insufficient validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and disruption of service.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to gain unauthorized access to the database, extract sensitive information, modify or delete data, and in some cases, execute administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the '/maintenance/add_maintenance_cost.php' file with a malicious payload in the 'id' parameter. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
