A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical malicious user to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the malicious user to disable UEFI Secure Boot. A successful exploit could allow the malicious user to bypass the signature validation checks that are done by UEFI Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.
