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-2024-20291 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-2024-20291/ (Markdown: https://insights.sbomify.com/CVE-2024-20291/index.md)","id":"CVE-2024-20291","markdown":"https://insights.sbomify.com/CVE-2024-20291/index.md","name":"CVE-2024-20291","record":{"aliases":["GHSA-wwgf-8wgf-pm54"],"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 ACLs on port channel subinterfaces to access protected network resources due to incorrect hardware programming.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"nx-os","vendor":"cisco"}],"cvss":{"score":5.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-284","name":"Improper Access Control"}],"description":"A vulnerability in the access control list (ACL) programming for port channel subinterfaces of Cisco Nexus 3000 and 9000 Series Switches in standalone NX-OS mode could allow an unauthenticated, remote attacker to send traffic that should be blocked through an affected device.\r\n\r This vulnerability is due to incorrect hardware programming that occurs when configuration changes are made to port channel member ports.
