Itsourcecode Courier Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the Itsoucecode Courier Management System version 1.0. The issue resides in the file '/manage_user.php', where the application improperly sanitizes the 'id' parameter before incorporating it into an SQL query. This flaw enables remote attackers to inject malicious SQL commands, potentially leading to unauthorized database access and manipulation.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, appended to the original SQL query of the vulnerable endpoint. This could result in unauthorized data access, data modification, and in some cases, executing commands on the server.

Reproduction

To reproduce this vulnerability, send a GET request to '/manage_user.php' with a crafted 'id' parameter that includes SQL injection payloads. The vulnerability can be verified by injecting a time-based payload, which will cause a delay in the response, indicating successful exploitation.

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 user input conforms to expected formats. Minimizing database user permissions can also help reduce the impact of potential exploits.
