CVE-2025-4800
HighSummary
Wtyczka MasterStudy LMS Pro dla WordPressa jest podatna na nieautoryzowane przesyłanie plików z powodu braku walidacji typu pliku w funkcji stm_lms_add_assignment_attachment we wszystkich wersjach do i włącznie z 4.7.0. Umożliwia to uwierzytelnionym atakującym, posiadającym dostęp na poziomie Subskrybenta i wyżej, przesyłanie dowolnych plików na serwer dotkniętej strony.
Risk Assessment
Podatność ta może prowadzić do zdalnego wykonania kodu, co stwarza poważne zagrożenie dla bezpieczeństwa serwera oraz danych przechowywanych na stronie. Atakujący mogą wykorzystać tę lukę do przejęcia kontroli nad systemem.
Recommendation
Zaleca się aktualizację wtyczki MasterStudy LMS Pro do najnowszej wersji, aby usunąć tę podatność. Dodatkowo warto wprowadzić dodatkowe mechanizmy zabezpieczeń, takie jak ograniczenie możliwości przesyłania plików przez użytkowników o niskich uprawnieniach.

Original NVD description (English source)
The MasterStudy LMS Pro plugin for WordPress is vulnerable to arbitrary file uploads due to a missing file type validation in the stm_lms_add_assignment_attachment function in all versions up to, and including, 4.7.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to upload arbitrary files on the affected site's server, which may make remote code execution possible.
