SourceCodester Client Database Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in SourceCodester Client Database Management System version 1.0. The issue resides in the file '/user_proposal_update_order.php', where the 'order_id' parameter is manipulated to inject malicious SQL code. This vulnerability allows attackers to interfere with SQL queries, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information. The vulnerability can be exploited remotely without any authentication.

Impact

Exploitation of this vulnerability allows attackers to execute arbitrary SQL commands, potentially leading to unauthorized access to the database, manipulation or deletion of data, and exposure of sensitive information. Additionally, according to the vulnerability's GitHub advisory, this SQL injection could be exploited to gain control over the entire system and disrupt services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/cdm/user_proposal_update_order.php' with an 'order_id' parameter that includes a crafted SQL payload. This payload should exploit the application's SQL query handling by injecting malicious SQL code that, for example, accesses database information through error-based SQL injection techniques.

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.
