CVE-2026-32634
HighSummary
Glances to narzędzie do monitorowania systemów, które przed wersją 4.5.2 w trybie Central Browser przechowywało niezweryfikowaną nazwę serwera i odkryty adres IP dla dynamicznych serwerów. W wyniku tego, atakujący w tej samej sieci lokalnej mógł podszyć się pod serwis Glances i przechwycić sekrety uwierzytelniające użytkowników.
Risk Assessment
Organizacja jest narażona na przechwycenie danych uwierzytelniających przez atakującego, co może prowadzić do nieautoryzowanego dostępu do systemów monitorowanych przez Glances. W szczególności, atakujący może uzyskać dostęp do poufnych informacji przechowywanych w aplikacji.
Recommendation
Zaleca się aktualizację Glances do wersji 4.5.2 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto rozważyć ograniczenie dostępu do sieci lokalnej, aby zminimalizować ryzyko ataków typu man-in-the-middle.

Original NVD description (English source)
Glances is an open-source system cross-platform monitoring tool. Prior to version 4.5.2, in Central Browser mode, Glances stores both the Zeroconf-advertised server name and the discovered IP address for dynamic servers, but later builds connection URIs from the untrusted advertised name instead of the discovered IP. When a dynamic server reports itself as protected, Glances also uses that same untrusted name as the lookup key for saved passwords and the global `[passwords] default` credential. An attacker on the same local network can advertise a fake Glances service over Zeroconf and cause the browser to automatically send a reusable Glances authentication secret to an attacker-controlled host. This affects the background polling path and the REST/WebUI click-through path in Central Browser mode. Version 4.5.2 fixes the issue.
