How the Exploit Works
The SQL Injection vulnerability occurs when the application fails to adequately sanitize user-supplied input before using it in an SQL query. An attacker can exploit this vulnerability by injecting malicious SQL commands into user input fields, which are then executed by the database. This can lead to unauthorized viewing, modification, or deletion of data in the database.
Conceptual Example Code
A conceptual example of exploiting this vulnerability might look like the following HTTP request:
POST /quizmaster/submit HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
quiz_id=1&answer=' OR '1'='1'; DROP TABLE users; --In this example, the attacker submits an answer to a quiz question that includes malicious SQL code. Instead of a quiz ID and an answer, the database receives and executes the command to drop the “users” table.
Remediation
Users of the affected versions of ExpressTech Systems Quiz And Survey Master are strongly advised to apply the vendor’s patch in order to mitigate this vulnerability. As a temporary measure, users can also employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to detect and block SQL injection attacks. However, these measures are not a substitute for patching the vulnerability at the source.
