Today, in addition to the 6 security advisories we are releasing, we want to call your attention to a new whitepaper we have just published addressing CVE-2019-0090, a vulnerability in the Intel® Converged Security Management Engine (CSME) that we first disclosed in May of last year.
CSME is an important part of overall system security and is an area where we continuously focus internal security research efforts to find and address issues proactively. For example, of the various CSME related vulnerabilities addressed in 2019, 87% were found by Intel, and the rest were submitted through our Bug Bounty program, meaning that all those vulnerabilities were found or disclosed as a result of Intel’s investment in security research.
CVE-2019-0090 was released as part of INTEL-SA-00213 in May 2019, and additional affected products were added to this CVE in February 2020. Following the latest update, external researchers posted information that generated questions from customers. The release of this whitepaper is intended to provide clarity around this issue and our mitigations. We are not aware of any real-world exploits of this issue.
Since the release of the security advisory, Intel’s guidance has remained the same:
- Applying latest Intel® CSME firmware and BIOS updates on affected systems with end of manufacturing set by the system manufacturer should mitigate local attacks. Physical attack might still be possible if Intel CSME Hardware based Anti-Rollback (ARB) feature is not supported by the system manufacturer.
- Physical ARB feature mitigates this kind of attack on newer Intel systems. It can be applied as part of a BIOS update for CSME 12 based platforms and newer, if such update is supported by system manufacturers.
- Intel recommends that end users adopt best security practices by installing updates as soon as they become available and being continually vigilant to detect and prevent intrusions and exploitations.
- For the latest update, you may refer to the security advisories published on https://www.intel.com/security. Intel® CSME latest firmware update may be obtained through your system manufacturer.
