- CWE-74 - Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
Summary
The Quiz And Survey Master plugin for WordPress is vulnerable to Arbitrary Shortcode Execution in versions up to and including 11.1.0. This is due to insufficient input sanitization and the execution of do_shortcode() on user-submitted quiz answer text. User-submitted answers pass through sanitize_text_field() and htmlspecialchars(), which only strip HTML tags but do not encode or remove shortcode brackets [ and ]. When quiz results are displayed, the plugin calls do_shortcode() on the entire results page output (including user answers), causing any injected shortcodes to be executed. This makes it possible for unauthenticated attackers to inject arbitrary WordPress shortcodes such as [qsm_result id=X] to access other users' quiz submissions without authorization, as the qsm_result shortcode lacks any authorization checks.

EPSS score ?
CWE
- CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
The Quiz and Survey Master (QSM) plugin for WordPress is vulnerable to SQL Injection via the 'merged_question' parameter in all versions up to, and including, 10.3.5. This is due to insufficient sanitization of user-supplied input before being used in a SQL query. The sanitize_text_field() function applied to the merged_question parameter does not prevent SQL metacharacters like ), OR, AND, and # from being included in the value, which is then directly concatenated into a SQL IN() clause without using $wpdb->prepare() or casting values to integers. This makes it possible for authenticated attackers, with Contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

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.

CWE
- CWE-89 - Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Summary
The Quiz And Survey Master – Best Quiz, Exam and Survey Plugin for WordPress plugin for WordPress is vulnerable to SQL Injection via the 'question_id' parameter in all versions up to, and including, 9.0.1 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 contributor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. CVE-2024-5606 appears to be a duplicate of this issue.

CWE
- CWE-352 - Cross-Site Request Forgery (CSRF)
Summary
The Quiz And Survey Master plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.0.8. This is due to missing nonce validation on the function associated with the qsm_remove_file_fd_question AJAX action. This makes it possible for unauthenticated attackers to delete arbitrary media files via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

CWE
- CWE-20 - Improper Input Validation
Summary
The Quiz and Survey Master plugin for WordPress is vulnerable to input validation bypass via the 'question[id]' parameter in versions up to, and including, 8.0.4 due to insufficient input validation that allows attackers to inject content other than the specified value (i.e. a number, file path, etc..). This makes it possible attackers to submit values other than the intended input type.

Summary
The Quiz and Survey Master plugin for WordPress is vulnerable to iFrame Injection via the 'question[id]' parameter in versions up to, and including, 8.0.4 due to insufficient input sanitization and output escaping that allowed iframe tags to be injected. This makes it possible for unauthenticated attackers to inject iFrames in pages that will execute whenever a user accesses an injected page.
