Tutor Lms – Elearning And Online Course Solution

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.0.7 via the `withdraw_method_field` parameter of the `tutor_save_withdraw_account` AJAX handler. This is due to the handler lacking any capability or role check, relying solely on a nonce, while also passing attacker-supplied values through `esc_sql()`, which replaces every `%` character with a 66-byte HMAC placeholder token before the data is serialized and stored via `update_user_meta()`; when the meta is later retrieved, the placeholder is collapsed back to a single `%`, leaving serialized string length declarations 65 bytes greater than the actual content, and because array keys originate from entirely unescaped POST field names, `unserialize()` over-reads into attacker-controlled bytes, allowing injection of an arbitrary serialized object stream. This makes it possible for authenticated attackers, with subscriber-level access and above, to achieve remote code execution on the server by triggering the `GuzzleHttp\Cookie\FileCookieJar` POP chain, reachable via the `spl_autoload_register` loader in `TUTOR\RestAPI` which loads the plugin's own bundled PayPal Composer autoloader, writing attacker-controlled content to an attacker-specified filename. This has an unauthenticated pathway when user registration is enabled, which is common for students and teachers to register, and it requires the monetization feature to be enabled.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via the 'coupon_code' parameter in all versions up to, and including, 4.0.1 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via Stored Quiz Answer Array in all versions up to, and including, 4.0.0 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 custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. The payload is stored at quiz-attempt time via the wp_ajax_tutor_quiz_abandon handler, but the injected SQL executes only when a privileged user or Tutor REST API key holder requests the /wp-json/tutor/v1/quiz-attempt-details/{id} endpoint, making this a second-order (stored) injection chain.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Lesson Attachment Title in all versions up to, and including, 3.9.13 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Tutor LMS – eLearning and online course solution plugin for WordPress is vulnerable to generic SQL Injection via the 'data' parameter in all versions up to, and including, 3.9.11 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 administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
