An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-36213 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- github.com/hashicorp/consul (Go): affected all versions; fixed in 1.10.1\n- github.com/hashicorp/consul (Go): affected all versions; fixed in 1.10.1\n- github.com/hashicorp/consul (Go): affected all versions; fixed in 1.10.1\n- consul (Bitnami): affected from 1.9.0; fixed in 1.9.8, 1.10.1\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-2021-36213/ (Markdown: https://insights.sbomify.com/CVE-2021-36213/index.md)","id":"CVE-2021-36213","markdown":"https://insights.sbomify.com/CVE-2021-36213/index.md","name":"CVE-2021-36213","record":{"aliases":["BIT-consul-2021-36213","GHSA-8h2g-r292-j8xh","GO-2022-0895","UBUNTU-CVE-2021-36213"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Service mesh software","requires_auth":"none","summary":"HashiCorp Consul fails open on specific L7 deny policies, allowing unauthorized L4 traffic bypassing intended security controls.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"consul","vendor":"hashicorp"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[],"description":"HashiCorp Consul and Consul Enterprise 1.9.0 through 1.10.0 default deny policy with a single L7 application-aware intention deny action cancels out, causing the intention to incorrectly fail open, allowing L4 traffic.
