Note


In IMM Server Firmware bundles prior to the 5.2(0.230040) release, X-Series BIOS images had major versions of 5.0 and 5.1.

Beginning with IMM Server Firmware 5.2(0.230040), the IMM and UCSM BIOS images will be common and numbered beginning with 4.3(2).

The resulting IMM BIOS Image major version sequence will follow 5.0 -> 5.1 -> 4.3 -> so on.


Overview

Cisco Intersight Infrastructure Services (IIS) enable the streamlined deployment, monitoring, management, and support of physical and virtual infrastructure. IIS supports Cisco Unified Computing System™ (UCS) servers and third-party devices. In addition, IIS provides the following advanced management and support capabilities along with global visibility of infrastructure health and status.

  • Telemetry data can be analyzed without any manual intervention when a problem occurs.

  • Service Request (SR) and a Return Material Authorization (RMA) are raised automatically.

IIS manages the following Cisco UCS servers:

  • C-Series Standalone servers

  • UCSM Managed Mode (UMM) B-Series, C-Series servers, and X-Series servers (FI-attached)

  • Intersight Managed Mode (IMM) B-Series, C-Series, and X-Series servers (FI-attached)

Defect ID - CSCwf30468

Cisco UCS C-Series M5 Rack Servers include an Intel® processor that is affected by the vulnerabilities identified by the following Common Vulnerability and Exposures (CVE) ID(s):

CVE-2022-40982—Information exposure through microarchitectural state after transient execution in certain vector execution units for some Intel® Processors may allow an authenticated user to potentially enable information disclosure through local access.

CVE-2022-43505—Insufficient control flow management in the BIOS firmware for some Intel® Processors may allow a privileged user to potentially enable denial of service through local access.

Defect ID - CSCwe96259

Cisco UCS C-Series Rack Servers are affected by the vulnerabilities identified by the following Common Vulnerability and Exposures (CVE) ID(s):

CVE-2023-20228—A vulnerability in the web-based management interface of Cisco IMC could allow an unauthenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.

Defect ID - CSCwf98321

Cisco UCS S-Series S3260 M4 Rack Servers are affected by the vulnerabilities identified by the following Common Vulnerability and Exposures (CVE) ID(s):

  • CVE-2022-38083—Improper initialization in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure through local access.

  • CVE-2022-43505—Insufficient control flow management in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable denial of service through local access.
