Description

Go Ethereum (aka geth) through 1.10.21 allows attackers to increase rewards by mining blocks in certain situations, and using a manipulation of time-difference values to achieve replacement of main-chain blocks, aka Riskless Uncle Making (RUM), as exploited in the wild in 2020 through 2022.

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/ethereum/go-ethereum, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of github.com/ethereum/go-ethereum for CVE-2022-37450. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    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.
