CVE-2026-27177
HighSummary
MajorDoMo zawiera podatność na przechowywane ataki XSS poprzez punkt końcowy /objects/?op=set, który jest celowo niezabezpieczony dla integracji urządzeń IoT. Wartości właściwości dostarczane przez użytkownika są przechowywane w bazie danych bez sanitizacji, co pozwala na ich wykonanie w panelu administracyjnym.
Risk Assessment
Atakujący może wykorzystać tę podatność do wykonania złośliwego kodu JavaScript w kontekście przeglądarki administratora, co może prowadzić do kradzieży sesji oraz przejęcia kontroli nad systemem. Dodatkowo, brak flagi HttpOnly w ciasteczku sesyjnym zwiększa ryzyko kradzieży sesji.
Recommendation
Zaleca się wprowadzenie sanitizacji danych wejściowych oraz zabezpieczenie punktu końcowego /objects/?op=set. Należy również dodać flagę HttpOnly do ciasteczek sesyjnych, aby zminimalizować ryzyko kradzieży sesji.

Original NVD description (English source)
MajorDoMo (aka Major Domestic Module) contains a stored cross-site scripting (XSS) vulnerability via the /objects/?op=set endpoint, which is intentionally unauthenticated for IoT device integration. User-supplied property values are stored raw in the database without sanitization. When an administrator views the property editor in the admin panel, the stored values are rendered without escaping in both a paragraph tag (SOURCE field) and a textarea element (VALUE field). The XSS fires on page load without requiring any click from the admin. Additionally, the session cookie lacks the HttpOnly flag, enabling session hijack via document.cookie exfiltration. An attacker can enumerate properties via the unauthenticated /api.php/data/ endpoint and poison any property with malicious JavaScript.
