Summary

The Quiz and Survey Master (QSM) – Easy Quiz and Survey Maker plugin for WordPress is vulnerable to time-based SQL Injection via the ‘is_linking’ parameter in all versions up to, and including, 10.3.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Risk Assessment

An attacker may gain access to sensitive data in the WordPress database, potentially leading to confidentiality and integrity breaches.

Recommendation

Update the QSM plugin to a version newer than 10.3.1 if available, or apply temporary mitigations such as restricting access to the functionality.
