GHSA-g7vp-j25f-h34p

MEDIUM

GHSA-g7vp-j25f-h34p is a medium-severity (CVSS 6.7) CWE-321 vulnerability in github.com/lf-edge/eve. O3 Security confirms whether GHSA-g7vp-j25f-h34p is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Go packages — download data is not available via public APIs for these ecosystems.

Description

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

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/lf-edge/eve. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/lf-edge/eve to 0.0.0-20220310190112-c0c966dc31e2 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-g7vp-j25f-h34p is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-g7vp-j25f-h34p is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-g7vp-j25f-h34p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
