Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-5089 in the wild and no public exploit code.\n\nAffected product: Arista Networks EOS / CloudVision eXchange (CVX). 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-2025-5089/ (Markdown: https://insights.sbomify.com/CVE-2025-5089/index.md)","id":"CVE-2025-5089","markdown":"https://insights.sbomify.com/CVE-2025-5089/index.md","name":"CVE-2025-5089","record":{"aliases":["GHSA-xmjq-j83c-q6g4"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"Arista EOS switch","requires_auth":"low_privilege","summary":"An attacker with high privileges can cause denial of service on Arista EOS switches or CVX servers by sending malformed messages, requiring CVX connectivity.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arista","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In a CVX cluster, an EOS switch connected to a CVX server is not resilient to certain malformed messages received from the connected CVX server. Similarly, the CVX server is not resilient to certain malformed messages received from the connected EOS switch. This leads to either a Sysdb agent crash on the EOS device causing a soft reset of the switch or agent crashes on the CVX server causing instability of the CVX cluster. An attacker could use this behavior to create a denial of service (DoS) scenario. Note that this would require the attacker to already have a high privilege access to the connected device to be able to send custom TCP packets. EOS switches that are not connected to a CVX server are not impacted.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Arista EOS SysDB Agent Denial of Service via Malformed CVX Client/Server Messages","id":"CVE-2025-5089","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":"Arista CloudVision Exchange Cluster Instability via Unexpected Switch Messages","id":"CVE-2025-5090"},"packages":[],"prev":{"headline":"Arista CloudVision Exchange (CVX) Cluster Privilege Escalation via MCS Redis Session","id":"CVE-2025-5088"},"products":["EOS / CloudVision eXchange (CVX)"],"published":"2026-06-05","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":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-06-09","vendors":["Arista Networks"]},"summary":"An attacker with high privileges can cause denial of service on Arista EOS switches or CVX servers by sending malformed messages, requiring CVX connectivity.","url":"https://insights.sbomify.com/CVE-2025-5089/"}
