Detailsinfo

A vulnerability was found in Insyde InsydeH2O up to 5.5. It has been classified as problematic. This affects some unknown functionality of the component TrEEConfigDriver. This is going to have an impact on integrity. The summary by CVE is:

An issue was discovered in TrEEConfigDriver in Insyde InsydeH2O with kernel 5.0 through 5.5. It can report false TPM PCR values, and thus mask malware activity. Devices use Platform Configuration Registers (PCRs) to record information about device and software configuration to ensure that the boot process is secure. (For example, Windows uses these PCR measurements to determine device health.) A vulnerable device can masquerade as a healthy device by extending arbitrary values into Platform Configuration Register (PCR) banks. This requires physical access to a target victim's device, or compromise of user credentials for a device. This issue is similar to CVE-2021-42299 (on Surface Pro devices).

The weakness was shared 10/19/2023. It is possible to read the advisory at insyde.com. This vulnerability is uniquely identified as CVE-2023-30633 since 04/13/2023. The technical details are unknown and an exploit is not publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2023-34997). Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
