How to Fix CVE-2023-43637

To remediate this vulnerability, upgrade all affected Github.com/lf edge/eve dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/lf-edge/eve fixed: 0.0.0-20220310190112-c0c966dc31e2 
Upgrade github.com/lf-edge/eve to 0.0.0-20220310190112-c0c966dc31e2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/lf-edge/eve

How to Check if You Are Affected

To determine whether your application is affected by CVE-2023-43637, inspect your project dependencies for Github.com/lf edge/eve:

inspect dependencies for github.com/lf-edge/eve

Analyze the terminal output to locate any version of Github.com/lf edge/eve in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.0.0-20220310190112-c0c966dc31e2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-321: Use of Hard-coded Cryptographic Key, where the product uses a hard-coded, unchangeable cryptographic key. 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 The deriveVaultKey function calls retrieveCloudKey which always returns "foobarfoobarfoobarfoobarfoobarfo". When merged with the randomly generated 32-byte key using mergeKeys (16 bytes from each), the last 16 bytes are always "arfoobarfoobarfo". This enables an attacker with physical access to the EVE-OS device to attempt to brute force the remaining 128 bits of key. ### Patches Fixed in 7.10 and 8.12.1-lts ### Workarounds None
