CVE-2026-44400
HighCVSS 8.1Summary
MailEnable Enterprise Premium w wersji 10.55 i wcześniejszych zawiera lukę w autoryzacji w mobilnym portalu WebAdmin, która pozwala atakującym na ominięcie kontroli uwierzytelniania poprzez ponowne wykorzystanie ciasteczek AuthenticationToken generowanych dla użytkowników o niskich uprawnieniach. Atakujący mogą uzyskać token z punktu logowania WebMail, używając parametru PersistentLogin i wykorzystać go w portalu WebAdmin do wykonywania działań administracyjnych z wysokimi uprawnieniami.
Risk Assessment
Luka ta stwarza poważne ryzyko dla organizacji, umożliwiając atakującym uzyskanie dostępu do funkcji administracyjnych bez odpowiednich uprawnień. Może to prowadzić do nieautoryzowanych zmian w systemie oraz naruszenia danych.
Recommendation
Zaleca się aktualizację MailEnable Enterprise Premium do najnowszej wersji, aby usunąć tę lukę. Dodatkowo, warto wprowadzić dodatkowe mechanizmy zabezpieczeń, takie jak monitorowanie sesji i weryfikacja uprawnień użytkowników.

Original NVD description (English source)
MailEnable Enterprise Premium 10.55 and earlier contains an improper authorization vulnerability in the WebAdmin mobile portal that allows attackers to bypass authentication checks by reusing AuthenticationToken cookies generated for low-privileged users. Attackers can obtain a token from the WebMail login endpoint using the PersistentLogin parameter and replay it against the WebAdmin portal to perform highly privileged administrative actions.
