CVE-2026-27178
HighSummary
MajorDoMo zawiera podatność typu stored cross-site scripting (XSS) poprzez wstrzykiwanie parametrów metod do shoutboxa. Umożliwia to nieautoryzowane wykonanie przechowywanych metod z parametrami kontrolowanymi przez atakującego, co prowadzi do wykonania złośliwego skryptu przy każdym odświeżeniu dashboardu.
Risk Assessment
Podatność ta stwarza ryzyko przejęcia sesji administratora poprzez wykradanie ciasteczek, co może prowadzić do nieautoryzowanego dostępu do systemu. Wysoka częstotliwość odświeżania widgetu zwiększa prawdopodobieństwo skutecznego ataku.
Recommendation
Zaleca się wprowadzenie odpowiednich mechanizmów sanitizacji danych wejściowych oraz ograniczenie dostępu do endpointu /objects/?method= tylko dla autoryzowanych użytkowników. Dodatkowo, warto zaktualizować system do najnowszej wersji, aby usunąć tę podatność.

Original NVD description (English source)
MajorDoMo (aka Major Domestic Module) contains a stored cross-site scripting (XSS) vulnerability through method parameter injection into the shoutbox. The /objects/?method= endpoint allows unauthenticated execution of stored methods with attacker-controlled parameters. Default methods such as ThisComputer.VolumeLevelChanged pass the user-supplied VALUE parameter directly into the say() function, which stores the message raw in the shouts database table without escaping. The shoutbox widget renders stored messages without sanitization in both PHP rendering code and HTML templates. Because the dashboard widget auto-refreshes every 3 seconds, the injected script executes automatically when any administrator loads the dashboard, enabling session hijack through cookie exfiltration.
