Vulnerability from variot - Updated: 2024-11-23 21:51

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. Cisco UCS C A series rack server contains a vulnerability related to digital signature verification.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Cisco UCS C-Series is a C series rack server from Cisco (USA). The following products and versions are affected: Firepower Management Center (FMC) 1000; Firepower Management Center (FMC) 2500; Firepower Management Center (FMC) 4500; Secure Network Server 3500 Series Appliances; Secure Network Server 3600 Series Appliances; Threat Grid 5504 Appliance

    "data": "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. Cisco UCS C A series rack server contains a vulnerability related to digital signature verification.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. Cisco UCS C-Series is a C series rack server from Cisco (USA). The following products and versions are affected: Firepower Management Center (FMC) 1000; Firepower Management Center (FMC) 2500; Firepower Management Center (FMC) 4500; Secure Network Server 3500 Series Appliances; Secure Network Server 3600 Series Appliances; Threat Grid 5504 Appliance",

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
