An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-5502 in the wild and no public exploit code.\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-2023-5502/ (Markdown: https://insights.sbomify.com/CVE-2023-5502/index.md)","id":"CVE-2023-5502","markdown":"https://insights.sbomify.com/CVE-2023-5502/index.md","name":"CVE-2023-5502","record":{"aliases":["GHSA-q5p5-569h-ccvx"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":true,"product_category":"Arista EOS","requires_auth":"none","summary":"A malicious supplicant can bypass 802.1x authentication on Arista EOS devices when routing is enabled on the access VLAN.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Arista","cpe":[],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"On affected platforms running Arista EOS with 802.1x authentication configured on the access/trunk ports, and routing enabled on the access VLAN of the ports, a malicious supplicant may be able to bypass the requirement to perform 802.1x authentication.","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":"Auth bypass in EOS","id":"CVE-2023-5502","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"BackWPup \u003c= 4.0.1 - Authenticated (Administrator+) Directory Traversal","id":"CVE-2023-5504"},"packages":[],"prev":{"headline":"Frauscher: FDS102 for FAdC/FAdCi remote code execution vulnerability","id":"CVE-2023-5500"},"products":["EOS"],"published":"2026-06-04","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":"2026-06-05","vendors":["Arista Networks"]},"summary":"A malicious supplicant can bypass 802.1x authentication on Arista EOS devices when routing is enabled on the access VLAN.","url":"https://insights.sbomify.com/CVE-2023-5502/"}
