itsourcecode Courier Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the itsourcecode Courier Management System version 1.0. The issue resides in the file /print_pdets.php, where the 'ids' parameter is not properly sanitized, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, but requires authentication.

Impact

Exploitation of this vulnerability allows for unauthorized database access, data manipulation, and potential leakage of sensitive information.

Reproduction

To reproduce this vulnerability, log into the application and navigate to the /print_pdets.php page. Once there, the 'ids' parameter can be manipulated to inject SQL payloads. This can be done using a boolean-based blind injection, by replacing the 'ids' parameter with a crafted SQL query that exploits the application's SQL query handling. Alternatively, a time-based blind injection can be performed by using a payload that causes the database to pause for a few seconds before responding, indicating that the injection was successful.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the application's security.
