It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-8870 exists.\n\nAffected product: Arista Networks EOS. 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-2025-8870/ (Markdown: https://insights.sbomify.com/CVE-2025-8870/index.md)","id":"CVE-2025-8870","markdown":"https://insights.sbomify.com/CVE-2025-8870/index.md","name":"CVE-2025-8870","record":{"aliases":["GHSA-8rvj-6hp5-gf5x"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Arista EOS","requires_auth":"none","summary":"An attacker with serial console access can cause an unexpected device reload, leading to denial of service on Arista EOS platforms.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arista","cpe":[],"cvss":{"score":5.6,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:H","version":"4.0"},"cwes":[{"id":"CWE-248","name":"Uncaught Exception"}],"description":"On affected platforms running Arista EOS, certain serial console input might result in an unexpected reload of the device.153","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Denial of service in EOS","id":"CVE-2025-8870","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Everest Forms (Pro) \u003c= 1.9.7 - Unauthenticated PHP Object Injection via PHAR Deserialization in Form Signature","id":"CVE-2025-8871"},"packages":[],"prev":{"headline":"Fallback tar extraction in pip doesn't check symbolic links point to extraction directory","id":"CVE-2025-8869"},"products":["EOS"],"published":"2025-11-14","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-11-14","vendors":["Arista Networks"]},"summary":"An attacker with serial console access can cause an unexpected device reload, leading to denial of service on Arista EOS platforms.","url":"https://insights.sbomify.com/CVE-2025-8870/"}
