Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-21954 in the wild and no public exploit code.\n\nAffected product: Anker. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2021-21954/ (Markdown: https://insights.sbomify.com/CVE-2021-21954/index.md)","id":"CVE-2021-21954","markdown":"https://insights.sbomify.com/CVE-2021-21954/index.md","name":"CVE-2021-21954","record":{"aliases":["GHSA-853q-qp3f-8m3v"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Home security hub","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary commands on Anker Eufy Homebase 2 devices via crafted network packets in the wifi_country_code_update function.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"eufy_homebase_2_firmware","vendor":"anker"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"A command execution vulnerability exists in the wifi_country_code_update functionality of the home_security binary of Anker Eufy Homebase 2 2.1.6.9h.
