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-2017-6655 in the wild and no public exploit code.\n\nAffected product: Cisco Nx-Os. 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-2017-6655/ (Markdown: https://insights.sbomify.com/CVE-2017-6655/index.md)","id":"CVE-2017-6655","markdown":"https://insights.sbomify.com/CVE-2017-6655/index.md","name":"CVE-2017-6655","record":{"aliases":["GHSA-ffjq-497x-2qq5"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Cisco NX-OS Switch","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a denial of service in Cisco NX-OS devices configured for FCoE by triggering a process reload.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"mds_9000_nx-os","vendor":"cisco"},{"product":"nx-os","vendor":"cisco"},{"product":"nx-os_for_nexus_5500_platform_switches","vendor":"cisco"},{"product":"nx-os_for_nexus_5600_platform_switches","vendor":"cisco"},{"product":"nx-os_for_nexus_7700_series_switches","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"A vulnerability in the Fibre Channel over Ethernet (FCoE) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition when an FCoE-related process unexpectedly reloads.
