  # Exploit Title: WordPress Plugin LifterLMS 4.21.0 - Stored Cross-Site Scripting (XSS) # Date: 2021-05-10 # Exploit Author: Captain_hook # Vendor Homepage: https://lifterlms.com/ # Software Link: https://github.com/gocodebox/lifterlms/releases/tag/4.21.0 # Version: LifterLMS < 4.21.1 # Tested on: ANY # CVE : CVE-2021-24308   #Summary:   The &apos;State&apos; field of the Edit profile page of the LMS by LifterLMS – Online Course, Membership & Learning Management System Plugin for WordPress plugin before 4.21.1 is not properly sanitised when output in the About section of the profile page, leading to a stored Cross-Site Scripting issue. This could allow low privilege users (such as students) to elevate their privilege via an XSS attack when an admin will view their profile.   #Proof_of_Concept:   1- As a Lowest Privilege user go to the edit account page of the LMS (e.g https://example.com/my-courses/edit-account/)   2- Put Your XSS payload in State parameter and save your edits, such as "><script>alert(/XSS/)</script>   3- The XSS will be stored and triggered in the about section of the profile: (e.ghttps://example.com/directory/[user_name]/) (Note): The XSS will also be triggered in the admin dashboard when viewing the user details, for example https://example.com/wp-admin/admin.php?page=llms-reporting&tab=students&stab=information&student_id=2   Refernces:   https://github.com/gocodebox/lifterlms/releases/tag/4.21.0
