CVE-2024-13835
HighSummary
Wtyczka Post Meta Data Manager dla WordPressa jest podatna na eskalację uprawnień w środowiskach multisite we wszystkich wersjach do 1.4.4 włącznie. Problem wynika z braku odpowiedniej weryfikacji istnienia instalacji multisite przed umożliwieniem dodawania lub modyfikowania metadanych użytkowników.
Risk Assessment
Zagrożenie polega na tym, że uwierzytelnieni atakujący z dostępem na poziomie Administratora mogą uzyskać podwyższone uprawnienia na subdomenach, które normalnie byłyby dla nich niedostępne. Może to prowadzić do nieautoryzowanego dostępu do wrażliwych danych.
Recommendation
Zaleca się aktualizację wtyczki Post Meta Data Manager do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt uprawnień użytkowników w środowisku multisite.

Original NVD description (English source)
The Post Meta Data Manager plugin for WordPress is vulnerable to multisite privilege escalation in all versions up to, and including, 1.4.4. This is due to the plugin not properly verifying the existence of a multisite installation prior to allowing user meta to be added/modified. This makes it possible for authenticated attackers, with Administrator-level access and above, to gain elevated privileges on subsites that would otherwise be inaccessible.
