CVE-2018-6622
7.1 · HIGHOverview
CVE-2018-6622 is a high-severity vulnerability affecting trustedcomputinggroup trusted_platform_module. It was published on August 17, 2018 and has a CVSS 3.0 base score of 7.1 (HIGH).
This vulnerability has a CVSS 3.0 base score of 7.1, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
An issue was discovered that affects all producers of BIOS firmware who make a certain realistic interpretation of an obscure portion of the Trusted Computing Group (TCG) Trusted Platform Module (TPM) 2.0 specification. An abnormal case is not handled properly by this firmware while S3 sleep and can clear TPM 2.0. It allows local users to overwrite static PCRs of TPM and neutralize the security features of it, such as seal/unseal and remote attestation.
Remediation
Check the references section for vendor advisories and patches from trustedcomputinggroup. Update trusted_platform_module to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
