An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2021-40407 in the wild since at least 18 Dec 2024.\n\nAffected product: Reolink Rlc-410w Firmware. 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-2021-40407/ (Markdown: https://insights.sbomify.com/CVE-2021-40407/index.md)","id":"CVE-2021-40407","markdown":"https://insights.sbomify.com/CVE-2021-40407/index.md","name":"CVE-2021-40407","record":{"aliases":["GHSA-3w42-xvwv-qc2q"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Reolink IP camera","requires_auth":"high_privilege","summary":"An attacker can execute arbitrary OS commands on Reolink RLC-410W cameras via unvalidated input in the DDNS settings API.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"talos","cpe":[{"product":"rlc-410w_firmware","vendor":"reolink"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:H/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":"An OS command injection vulnerability exists in the device network settings functionality of reolink RLC-410W v3.0.0.136_20121102.
