CVE-2019-1736 (GCVE-0-2019-1736)

Vulnerability from cvelistv5

Published

2020-09-23 00:26

Modified

2024-11-13 18:05

Severity ?

6.2 (Medium) - CVSS:3.0/AV:P/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-347

Summary

A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical attacker 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 attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker 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.
