Description

HashiCorp Consul and Consul Enterprise 1.8.0 through 1.9.14, 1.10.7, and 1.11.2 has Uncontrolled Resource Consumption. Clusters with at least one ingress gateway configured may allow a user with service:write permission to register a specifically-defined service that can cause the Consul server to panic and shutdown. Versions 1.9.15, 1.10.8, and 1.11.3 contain patches for the problem.

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

  2. Fix

    Update github.com/hashicorp/consul to 1.9.15 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2022-24687 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.
