Acer-Antworten Security & Vulnerabilities

Sicherheitslücke bezüglich einer Sicherheitslücke, die Änderungen an den Secure Boot-Einstellungen ermöglichen kann

DETAILS ZUR ANFÄLLIGKEIT

Forscher haben eine Schwachstelle identifiziert, die Änderungen der Secure Boot-Einstellungen durch das Erstellen von NVRAM-Variablen ermöglichen kann (der tatsächliche Wert der Variablen ist nicht wichtig, nur die Existenz wird von den betroffenen Firmware-Treibern überprüft).

Referenznummer: CVE-2022-4020

Betroffene Modelle: Acer Aspire A315-22, A115-21, A315-22G, Extensa EX215-21 und EX215-21G

Auswirkungen

Durch die Deaktivierung der Secure-Boot-Funktion kann ein Angreifer seinen eigenen unsignierten, bösartigen Bootloader laden und so die absolute Kontrolle über den Ladevorgang des Betriebssystems erlangen. Auf diese Weise können sie Schutzmaßnahmen deaktivieren oder umgehen, um ihre eigenen Nutzdaten unbemerkt mit den Systemprivilegien zu verteilen.

Auflösung

Acer empfiehlt, Ihr BIOS auf Version 1.11 oder neuer zu aktualisieren, um dieses Problem zu beheben. Sie können das neueste BIOS von der Support-WebsiteAcer herunterladen.
