Description

The Lightning Network Daemon (lnd) - is a complete implementation of a Lightning Network node. A parsing vulnerability in lnd's onion processing logic and lead to a DoS vector due to excessive memory allocation. The issue was patched in lnd v0.17.0. Users should update to a version > v0.17.0 to be protected. Users unable to upgrade may set the --rejecthtlc CLI flag and also disable forwarding on channels via the UpdateChanPolicyCommand, or disable listening on a public network interface via the --nolisten flag as a mitigation.

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/lightningnetwork/lnd, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update github.com/lightningnetwork/lnd to 0.17.0-beta or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-38359 is resolved across your whole dependency graph.

  3. Workarounds

    Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
