An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-20120 in the wild and no public exploit code.\n\nAffected product: Arris SurfBoard SB8200. 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-2021-20120/ (Markdown: https://insights.sbomify.com/CVE-2021-20120/index.md)","id":"CVE-2021-20120","markdown":"https://insights.sbomify.com/CVE-2021-20120/index.md","name":"CVE-2021-20120","record":{"aliases":["GHSA-mmqp-272f-v3vw"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["data_modify","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Arris Surfboard SB8200","requires_auth":"none","summary":"Attackers can perform unauthorized configuration changes, such as resetting the admin password, via CSRF attacks on the Arris Surfboard SB8200 web interface.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"tenable","cpe":[{"product":"arris_surfboard_sb8200_firmware","vendor":"commscope"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"The administration web interface for the Arris Surfboard SB8200 lacks any protections against cross-site request forgery attacks.
