CVE-2023-30633

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...

CVE-2023-30633

CVE-2023-30633 affects Insyde InsydeH2O’s TrEEConfigDriver (kernel 5.0–5.5). The issue allows reporting of false TPM PCR values, enabling a device to masquerade as healthy by extending arbitrary data into PCR banks. Impact depends on PCR integrity, potentially masking malware activity; exploit re...

CVE-2023-43634

When sealing/unsealing the “vault” key, a list of PCRs is used, which defines which PCRs are used. In a previous project, CYMOTIVE found that the configuration is not protected by the secure boot, and in response Zededa implemented measurements on the config partition that was mapped to PCR 13. I...

CVE-2023-43633 Debug Functions Unlockable Without Triggering Measured Boot

On boot, the Pillar eve container checks for the existence and content of “/config/GlobalConfig/global.json”. If the file exists, it overrides the existing configuration on the device on boot. This allows an attacker to change the system’s configuration, which also includes some debug functions...

CVE-2023-43634 Config Partition Not Protected by Measured Boot

GHSA-5JVG-8J6F-VPMC Duplicate Advisory: EVE Doesn't Measure Config Partition From 2 Fronts

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-phcg-h58r-gmcq. This link is maintained to preserve external references. Original Description PCR14 is not in the list of PCRs that seal/unseal the “vault” key, but due to the change that was implemented in comm...

Duplicate Advisory: EVE Seals Vault Key With SHA1 PCRs

CVE-2023-43636

In EVE OS, the “measured boot” mechanism prevents a compromised device from accessing the encrypted data located in the vault. As per the “measured boot” design, the PCR values calculated at different stages of the boot process will change if any of their respective parts are changed. This...

CVE-2023-43635 Vault Key Sealed With SHA1 PCRs

Vault Key Sealed With SHA1 PCRs The measured boot solution implemented in EVE OS leans on a PCR locking mechanism. Different parts of the system update different PCR values in the TPM, resulting in a unique value for each PCR entry. These PCRs are then used in order to seal/unseal a key from the...

CVE-2023-43630 Config Partition Not Measured From 2 Fronts

PCR14 is not in the list of PCRs that seal/unseal the “vault” key, but due to the change that was implemented in commit “7638364bc0acf8b5c481b5ce5fea11ad44ad7fd4”, fixing this issue alone would not solve the problem of the config partition not being measured correctly. Also, the “vault” key is...
