CyberRota Analysis
AI-GeneratedCisco UCS Servers and UCS-based appliances are vulnerable due to a flaw in their UEFI Shell implementation, which allows attackers—either authenticated users with valid credentials or unauthenticated individuals with physical access—to bypass UEFI Secure Boot validation. This could enable them to manipulate the preboot environment and execute unauthorized software, posing a significant security risk. Organizations using affected Cisco products should prioritize remediation to safeguard against potential exploitation.

Original NVD Description
A vulnerability in the Unified Extensible Firmware Interface (UEFI) Shell implementation of Cisco UCS Servers and UCS-based appliances could allow an authenticated attacker with valid credentials for a user account with the role of user or admin or an unauthenticated attacker with physical access to an affected device to bypass UEFI Secure Boot validation checks and execute unauthorized software. This vulnerability is due to the availability of memory write commands in the UEFI Shell while UEFI Secure Boot is enabled on a device. An attacker could exploit this vulnerability by selecting the UEFI Shell boot option at boot time and using available shell commands to modify UEFI memory variables. A successful exploit could allow the attacker to manipulate the preboot environment, overwrite UEFI Secure Boot-related memory values, and execute unauthorized software on the affected device.
