What it is

⚡ Authenticated attackers can wreak havoc on your e-learning platform! With a little manipulative finesse, they're able to modify or delete any course they don't own! 🔥 Think of it like a restaurant where a few waiters can not only take orders but also change the whole menu! If they're not checked properly, they could serve up whatever dish they fancy, even if it’s not on their table! In this scenario, an attacker could sneak in and change course materials, delete courses, or even mess with student access. It’s a recipe for chaos—students may lose track of their courses, and educators may find their work undone!

Put simply

Think of it like a restaurant where a few waiters can not only take orders but also change the whole menu! If they're not checked properly, they could serve up whatever dish they fancy, even if it’s not on their table! This vulnerability arises from insecure direct object references (IDOR) due to missing authorization checks in key Tutor LMS functions, allowing users with Tutor Instructor-level access to modify or delete courses based on manipulated course IDs.

What to do

In this scenario, an attacker could sneak in and change course materials, delete courses, or even mess with student access. It’s a recipe for chaos—students may lose track of their courses, and educators may find their work undone! To safeguard your e-learning platform, immediately update Tutor LMS to version 3.9.6 or later. Additionally, implement strict object-level authorization checks to prevent unauthorized modifications. Regularly audit your access control measures for added security. You've got this! With these steps, you can secure your platform and keep learning safe and sound! 🛡️
