 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. |

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.
