Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-922: Insecure Storage of Sensitive Information, where the product stores sensitive information without properly limiting read or write access by unauthorized actors. In Github.com/lf edge/eve, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact Config partition measurement was moved from PCR 13 to PCR 14 in a commit, but PCR 14 was not added to the list of PCRs that seal/unseal the vault key. As a result, an attacker can remove the disk, use another server to modify the files in the config partition, and then re-insert the disk. ### Patches Fixed in EVE version 9.4.3-lts ### Workarounds None (apart from preventing physical access to the device) ### Resources https://help.zededa.com/hc/en-us/articles/43295940828827-TPM-PCR-Index-Security-Implications https://github.com/lf-edge/eve/commit/d9383a7ee4e1c39f5c8c6d4a63cb2ebd00695e8a
