An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-0845 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/consul (Go): affected from 1.14.0; fixed in 1.14.5\n- github.com/hashicorp/consul (Go): affected from 1.14.0; fixed in 1.14.5\n- github.com/hashicorp/consul (Go): affected from 1.14.0; fixed in 1.14.5\n- consul (Bitnami): affected all versions; fixed in 1.14.5\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-2023-0845/ (Markdown: https://insights.sbomify.com/CVE-2023-0845/index.md)","id":"CVE-2023-0845","markdown":"https://insights.sbomify.com/CVE-2023-0845/index.md","name":"CVE-2023-0845","record":{"aliases":["BIT-consul-2023-0845","GHSA-wj6x-hcc2-f32j","GO-2023-1639","UBUNTU-CVE-2023-0845"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Service mesh software","requires_auth":"high_privilege","summary":"Authenticated users with write permissions can crash Consul servers and agents by triggering a null pointer dereference in peering configurations.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HashiCorp","cpe":[{"product":"consul","vendor":"hashicorp"}],"cvss":{"score":4.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Consul and Consul Enterprise allowed an authenticated user with service:write permissions to trigger a workflow that causes Consul server and client agents to crash under certain circumstances.
