How the Exploit Works

The vulnerability lies in the id parameter of the ID Generator system’s admin page. By manipulating the id parameter value, an attacker can inject malicious SQL commands into the system. These commands may allow unauthorized access, data manipulation, or even a system takeover. The absence of proper sanitization of user-supplied inputs enables this exploit.

Conceptual Example Code

Here is a conceptual example of how an attacker might exploit this vulnerability:

GET /id_generator/admin/?page=generate/index&id=1 UNION SELECT ALL FROM users -- HTTP/1.1
Host: target.example.com

This HTTP GET request uses an SQL UNION operator to combine the results of the original query (which was intended to fetch a single ID) with a second query that retrieves all data from the ‘users’ table. The ‘–‘ at the end of the request is an SQL comment, which causes the system to ignore any following text. This could allow the attacker to bypass any additional parameters that the system might append to the query.

Prevention and Mitigation

The best course of action for administrators of the Sourcecodester Online ID Generator System 1.0 is to apply the vendor’s patch as soon as possible. In the absence of a patch, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as temporary mitigation. It is also recommended to regularly update and patch systems, as well as to use input validation and prepared statements to prevent SQL injection attacks.
