The Quiz Maker plugin for WordPress is vulnerable to time-based SQL Injection via the 'ays_questions' parameter in all versions up to, and including, 6.5.8.3 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.

command action=ays_finish_quiz

• → Detect time-based blind SQL injection attempts targeting the 'ays_questions' POST parameter on WordPress Quiz Maker plugin endpoints; look for requests with anomalous sleep/delay payloads (response duration >= 6 seconds) returning HTTP 200. ↗
• → Monitor POST requests containing 'action=ays_finish_quiz' with suspicious values in the 'ays_questions' parameter (e.g., injected SQL syntax such as '0,6,0)]=').
• → Exploitation is unauthenticated; no session or authentication cookie is required. Flag any unauthenticated requests to wp-admin/admin-ajax.php with action=ays_finish_quiz and a malformed ays_questions value.

• · All versions up to and including 6.5.8.3 of the Quiz Maker WordPress plugin are affected; ensure version-based detection rules are scoped accordingly. ↗
• · The time-based detection heuristic (duration >= 6 seconds) may produce false positives on slow servers; tune threshold based on baseline response times.
