CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

A vulnerability, which was classified as critical, was found in Intel Manageability Engine up to 11.20. This affects an unknown function of the component Kernel. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in kernel in Intel Manageability Engine Firmware 11.0/11.5/11.6/11.7/11.10/11.20 allow attacker with local access to the system to execute arbitrary code.

The bug was discovered 11/20/2017. The weakness was disclosed 11/20/2017 with Positive Technologies as INTEL-SA-00086 as confirmed security advisory (Website). It is possible to read the advisory at security-center.intel.com. This vulnerability is uniquely identified as CVE-2017-5705 since 02/01/2017. Attacking locally is a requirement. The successful exploitation requires a authentication. The technical details are unknown and an exploit is not publicly available. The advisory points out:

In response to issues identified by external researchers, Intel has performed an in-depth comprehensive security review of our Intel® Management Engine (ME), Intel® Server Platform Services (SPS), and Intel® Trusted Execution Engine (TXE) with the objective of enhancing firmware resilience. As a result, Intel has identified security vulnerabilities that could potentially place impacted platforms at risk.

The commercial vulnerability scanner Qualys is able to test this issue with plugin 38694 (Intel Management Engine Multiple Privilege Escalation And Buffer Overflow Vulnerabilities).

Upgrading eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.
