CVE-2023-4973Public exploitNetwork attack vector

Browser script execution via crafted filter parameters

Published Sep 15, 2023 · Updated Aug 2, 2024

Cross-site scripting in Academy LMS 6.2 on Windows allows remote attackers to execute script through crafted filter requests. The GET parameter handler at /academy/tutor/filter processes searched_word and three array-valued search parameters without neutralizing script-capable input during page generation. NVD treats the request as unauthenticated while the CNA requires low privileges; both assessments require another user to open it.
