Description

Incorrect permission assignment for critical resource for some System Firmware Update Utility (SysFwUpdt) for Intel(R) Server Boards and Intel(R) Server Systems Based before version 16.0.12. within Ring 3: User Applications may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires passive user interaction. The potential vulnerability may impact the confidentiality (high), integrity (high) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
