itsourcecode Construction Management System SQL Injection Vulnerability

A SQL injection vulnerability exists in the itsourcecode Construction Management System version 1.0, specifically within the borrowedtool.php file. The issue arises because the application does not properly sanitize or validate the 'code' parameter, allowing authenticated attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, 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. This could result in unauthorized data access, data modification, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, log into the application and navigate to borrowedtool.php. Once there, send a GET request with a crafted 'code' parameter that includes SQL injection payloads. The application will execute the injected SQL code, demonstrating the vulnerability.

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.
