It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-20143 in the wild and no public exploit code.\n\nAffected product: Gryphon Tower router. 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-2021-20143/ (Markdown: https://insights.sbomify.com/CVE-2021-20143/index.md)","id":"CVE-2021-20143","markdown":"https://insights.sbomify.com/CVE-2021-20143/index.md","name":"CVE-2021-20143","record":{"aliases":["GHSA-rq39-fwwc-45gh"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Gryphon Tower router","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary commands as root on Gryphon Tower routers via the controller_server service.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"gryphon_tower_firmware","vendor":"gryphonconnect"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"An unauthenticated command injection vulnerability exists in the parameters of operation 48 in the controller_server service on Gryphon Tower routers.
