Descriptions

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in ExpressTech Quiz And Survey Master.This issue affects Quiz And Survey Master: from n/a through 8.1.4.

Neutralización inadecuada de elementos especiales utilizados en una vulnerabilidad de comando SQL ("Inyección SQL") en ExpressTech Quiz And Survey Master. Este problema afecta a Quiz And Survey Master: desde n/a hasta 8.1.4.

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.
