Name of the Vulnerable Software and Affected Versions System Firmware Update Utility (SysFwUpdt) for some Intel(R) Server Boards and Intel(R) Server Systems Based on Intel(R) 621A Chipset versions prior to 16.0.7

Description The issue is related to an unquoted search path in the software installer, which may allow an authenticated user to potentially enable escalation of privilege via local access. This could potentially impact Intel(R) Server Boards and Intel(R) Server Systems Based on Intel(R) 621A Chipset.

Recommendations For versions prior to 16.0.7, update to version 16.0.7 or later to resolve the issue. As a temporary workaround, consider restricting local access to the System Firmware Update Utility (SysFwUpdt) to minimize the risk of exploitation.
