Description Preview

CVE-2020-8749 is an out-of-bounds read vulnerability (CWE-125) affecting the subsystem for Intel Active Management Technology (AMT). This vulnerability exists in versions before 11.8.80, 11.12.80, 11.22.80, 12.0.70, and 14.0.45. The flaw allows an unauthenticated user to potentially escalate privileges through adjacent access. This vulnerability could enable attackers to access sensitive information or gain elevated privileges on affected systems.

Overview

Intel Active Management Technology (AMT) is a feature in Intel processors that allows remote management of computers. The vulnerability identified as CVE-2020-8749 is an out-of-bounds read issue in the AMT subsystem. This type of vulnerability occurs when software reads data past the end of the intended buffer, potentially exposing sensitive information. In this case, an unauthenticated attacker with adjacent network access could exploit this vulnerability to escalate privileges on the affected system. The vulnerability affects multiple versions of Intel AMT, potentially exposing a wide range of systems to security risks.

Remediation

To address this vulnerability, organizations should:

  1. Update Intel AMT to the following versions or later:
    • Version 11.8.80
    • Version 11.12.80
    • Version 11.22.80
    • Version 12.0.70
    • Version 14.0.45
  2. Follow Intel's guidance provided in the security advisory Intel-SA-00391.
  3. If immediate patching is not possible, consider implementing network segmentation to limit adjacent access to systems running vulnerable Intel AMT versions.
  4. Monitor systems for any unusual activities that might indicate exploitation attempts.
  5. NetApp customers should refer to the NetApp security advisory NTAP-20201113-0003 for specific guidance related to their products.
