CVE-2021-47726
HighSummary
Router bezprzewodowy NuCom 11N w wersji 5.07.90 zawiera podatność na eskalację uprawnień, która pozwala użytkownikom bez uprawnień na dostęp do danych logowania administratora poprzez punkt końcowy kopii zapasowej konfiguracji. Atakujący mogą wysłać spreparowane żądanie HTTP GET do strony kopii zapasowej konfiguracji z określonym ciasteczkiem, aby odzyskać i zdekodować hasło administratora w formacie Base64.
Risk Assessment
Podatność ta stwarza ryzyko nieautoryzowanego dostępu do konta administratora, co może prowadzić do pełnej kontroli nad urządzeniem i jego konfiguracją. Może to skutkować poważnymi konsekwencjami dla bezpieczeństwa sieci organizacji.
Recommendation
Zaleca się aktualizację oprogramowania routera do najnowszej wersji, która eliminuje tę podatność. Dodatkowo, warto ograniczyć dostęp do strony kopii zapasowej konfiguracji oraz monitorować logi w celu wykrycia potencjalnych prób ataków.

- CVE-2026-94083Critical
In Suricata before 8.0.7, a type confusion in DoH2 can cause an invalid free because cleanup code for HTTP2 state runs even though the actual state is HTTP1 (when there is a DoH2 request with an HTTP1 to HTTP2 upgrade). This requires app-layer.protocols.doh2 to be enabled, which is default in 8.x versions.
