Quiz and Survey Master <= 8.1.4 - Unauthenticated SQL Injection
The Quiz and Survey Master plugin for WordPress is vulnerable to SQL Injection via the 'question_ids_[XX]' cookie in versions up to, and including, 8.1.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This requires the 'Random Questions' setting to be enabled for a given quiz to be exploitable.
