An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-3072 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/nomad (Go): affected from 0.7.0; fixed in 1.4.11, 1.5.6\n- github.com/hashicorp/nomad (Go): affected from 0.7.0; fixed in 1.4.11\n- github.com/hashicorp/nomad (Go): affected from 0.7.0; fixed in 1.4.11\n- github.com/hashicorp/nomad (Go): affected from 1.5.0; fixed in 1.5.6\n- github.com/hashicorp/nomad (Go): affected from 1.5.0; fixed in 1.5.6\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-2023-3072/ (Markdown: https://insights.sbomify.com/CVE-2023-3072/index.md)","id":"CVE-2023-3072","markdown":"https://insights.sbomify.com/CVE-2023-3072/index.md","name":"CVE-2023-3072","record":{"aliases":["GHSA-rpvr-38xv-xvxq","GO-2024-2670","UBUNTU-CVE-2023-3072"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["privilege_escalation","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HashiCorp Nomad","requires_auth":"high_privilege","summary":"Attackers can bypass ACL restrictions and access unexpected resources due to improper handling of unlabeled policy blocks in HashiCorp Nomad.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[{"product":"nomad","vendor":"hashicorp"}],"cvss":{"score":4.1,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-266","name":"Incorrect Privilege Assignment"}],"description":"HashiCorp Nomad and Nomad Enterprise 0.7.0 up to 1.5.6 and 1.4.10 ACL policies using a block without a label generates unexpected results.
