Itsourcecode Construction Management System SQL Injection Vulnerability in Parameter Handler

A SQL injection vulnerability exists in the Itsourcecode Construction Management System version 1.0, specifically within the Parameter Handler component. The issue is located in the '/borrowedequip.php' file, where the 'emp_id' parameter is not properly sanitized or validated before being used in SQL queries. This flaw allows authenticated attackers to inject malicious SQL code, potentially leading to unauthorized database access, data manipulation, and other serious security risks.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can manipulate database queries to access, modify, or delete data. This could also lead to unauthorized access to sensitive information or disruption of service.

Reproduction

To reproduce this vulnerability, log into the application with valid credentials. Then, send a request to the '/borrowedequip.php' file with the 'emp_id' parameter manipulated to include a crafted SQL payload. The injection can be verified by observing the application's response, which may indicate successful exploitation, such as a delay in response time if a time-based blind injection is used.

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.
