Attack Chain

1. An attacker identifies the vulnerable play.php script within the MOGG web simulator.
2. The attacker crafts a malicious SQL payload designed to extract data or manipulate the database.
3. The attacker sends a GET request to play.php, embedding the SQL payload in the id parameter (e.g., play.php?id=1'+UNION+SELECT+username,password+FROM+users--).
4. The web application fails to properly sanitize the input from the id parameter.
5. The application executes the attacker’s injected SQL code against the database.
6. The database processes the malicious query and returns the requested sensitive information.
7. The attacker captures the database response containing the extracted data (e.g., usernames, passwords).
8. The attacker uses the extracted data for further malicious activities, such as unauthorized access or data breaches.

Impact

Successful exploitation of this SQL injection vulnerability can lead to the exposure of sensitive data, including usernames, passwords, and potentially other confidential information stored in the database. An attacker could leverage this access to compromise user accounts, gain unauthorized access to the system, or perform further malicious activities. Given the unauthenticated nature of the vulnerability, the risk is significantly elevated, potentially impacting all users of the MOGG web simulator Script.

Recommendation

• Apply appropriate input validation and sanitization to the id parameter in play.php to prevent SQL injection attacks.
• Deploy the Sigma rule Detect MOGG Web Simulator SQL Injection Attempt to identify and block malicious requests targeting the vulnerable play.php script.
• Monitor web server logs for suspicious GET requests to play.php containing SQL injection payloads.
• Consider using parameterized queries or prepared statements to prevent SQL injection vulnerabilities.
