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-2025-20163 in the wild and no public exploit code.\n\nAffected product: Cisco Data Center Network Manager. 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-2025-20163/ (Markdown: https://insights.sbomify.com/CVE-2025-20163/index.md)","id":"CVE-2025-20163","markdown":"https://insights.sbomify.com/CVE-2025-20163/index.md","name":"CVE-2025-20163","record":{"aliases":["GHSA-435c-q8rw-j678"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Nexus Dashboard Fabric Controller","requires_auth":"none","summary":"An attacker can perform a man-in-the-middle attack to impersonate managed devices and capture user credentials due to insufficient SSH host key validation.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"nexus_dashboard","vendor":"cisco"}],"cvss":{"score":8.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-322","name":"Key Exchange without Entity Authentication"}],"description":"A vulnerability in the SSH implementation of Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an unauthenticated, remote attacker to impersonate Cisco NDFC-managed devices.\r\n\r\nThis vulnerability is due to insufficient SSH host key validation.
