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-2024-20371 in the wild and no public exploit code.\n\nAffected product: Cisco Nexus 3550 System Software. 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-2024-20371/ (Markdown: https://insights.sbomify.com/CVE-2024-20371/index.md)","id":"CVE-2024-20371","markdown":"https://insights.sbomify.com/CVE-2024-20371/index.md","name":"CVE-2024-20371","record":{"aliases":["GHSA-q7hr-x75r-2mp7"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Nexus switch","requires_auth":"none","summary":"Unauthenticated remote attackers can bypass ACL restrictions to reach the management interface during device reboot on Cisco Nexus 3550-F switches.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-264","name":null}],"description":"A vulnerability in the access control list (ACL) programming of Cisco Nexus 3550-F Switches could allow an unauthenticated, remote attacker to send traffic that should be blocked to the management interface of an affected device.\u0026nbsp;\r\n\r\nThis vulnerability exists because ACL deny rules are not properly enforced at the time of device reboot.
