WID-SEC-W-2024-3610
Vulnerability from csaf_certbund - Published: 2024-12-04 23:00 - Updated: 2024-12-04 23:00Es besteht eine Schwachstelle in Cisco NX-OS, Cisco Nexus, Cisco Unified Computing System (UCS) und Cisco MDS 9000. Dieser Fehler existiert im Bootloader der Cisco NX-OS Software wegen unsicherer Bootloader-Einstellungen. Durch die Ausführung einer Reihe von Bootloader-Befehlen kann ein Angreifer mit physischem Zugriff diese Schwachstelle ausnutzen, um die Überprüfung der NX-OS-Image-Signatur zu umgehen.
