A potential local bypass of security restrictions vulnerability has been identified in HPE ProLiant DL20 Gen10, HPE ProLiant ML30 Gen10, and HPE ProLiant MicroServer Gen10 Plus server's system ROMs prior to version 2.52. The vulnerability could be locally exploited to cause disclosure of sensitive information, denial of service (DoS), and/or compromise system integrity.

TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access.

The HPE-provided Windows firmware installer for certain Gen9, Gen8, G7,and G6 HPE servers allows local disclosure of privileged information. This issue was resolved in previously provided firmware updates as follows. The HPE Windows firmware installer was updated in the system ROM updates which also addressed the original Spectre/Meltdown set of vulnerabilities. At that time, the Windows firmware installer was also updated in the versions of HPE Integrated Lights-Out 2, 3, and 4 (iLO 2, 3, and 4) listed in the security bulletin. The updated HPE Windows firmware installer was released in the system ROM and HPE Integrated Lights-Out (iLO) releases documented in earlier HPE Security Bulletins: HPESBHF03805, HPESBHF03835, HPESBHF03831. Windows-based systems that have already been updated to the system ROM or iLO versions described in these security bulletins require no further action.
