Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-37218 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/nomad (Go): affected all versions; fixed in 1.0.10, 1.1.4\n- github.com/hashicorp/nomad (Go): affected all versions; fixed in 1.0.10\n- github.com/hashicorp/nomad (Go): affected all versions; fixed in 1.0.10\n- github.com/hashicorp/nomad (Go): affected from 1.1.0; fixed in 1.1.4\n- github.com/hashicorp/nomad (Go): affected from 1.1.0; fixed in 1.1.4\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2021-37218/ (Markdown: https://insights.sbomify.com/CVE-2021-37218/index.md)","id":"CVE-2021-37218","markdown":"https://insights.sbomify.com/CVE-2021-37218/index.md","name":"CVE-2021-37218","record":{"aliases":["GHSA-c8x3-rg72-fwwg","GO-2022-0591","UBUNTU-CVE-2021-37218"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"HashiCorp Nomad","requires_auth":"low_privilege","summary":"Non-server agents with valid certificates can access server-only functionality, leading to privilege escalation in HashiCorp Nomad.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nomad","vendor":"hashicorp"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"HashiCorp Nomad and Nomad Enterprise Raft RPC layer allows non-server agents with a valid certificate signed by the same CA to access server-only functionality, enabling privilege escalation.
