CVE-2023-43631 SSH as Root Unlockable Without Triggering Measured Boot

On boot, the Pillar eve container checks for the existence and content of “/config/authorizedkeys”. If the file is present, and contains a supported public key, the container will go on to open port 22 and enable sshd with the given keys as the authorized keys for root login. An attacker could...

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

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-2023-43634

CVE-2023-43634 relates to the EVE project: the config partition is measured for TPM PCRs used to seal/unseal the vault key. A change moved the config partition measurement from PCR 13 to PCR 14, but PCR 14 was not added to the sealing/unsealing list, making PCR 14’s measurement effectively redund...

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...

CVE-2023-43630

CVE-2023-43630 documents a TPM/Measured Boot issue in the EVE project (lf-edge/eve) where PCR14 is not in the sealing/unsealing list for the vault key, and the vault key is sealed with SHA1 PCRs instead of SHA256. A code change (commit 7638364bc0acf8b5c481b5ce5fea11ad44ad7fd4) meant that PCR14 up...
