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-2019-1804 in the wild and no public exploit code.\n\nAffected product: Cisco NX-OS Software for Nexus 9000 Series Fabric Switches ACI Mode 11.0.1b. 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-2019-1804/ (Markdown: https://insights.sbomify.com/CVE-2019-1804/index.md)","id":"CVE-2019-1804","markdown":"https://insights.sbomify.com/CVE-2019-1804/index.md","name":"CVE-2019-1804","record":{"aliases":["GHSA-9hxx-97w4-fh95"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Nexus switch","requires_auth":"none","summary":"An unauthenticated remote attacker can gain root access to Cisco Nexus 9000 switches via IPv6 using a default SSH key.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"nexus_93108tc-ex_firmware","vendor":"cisco"},{"product":"nexus_93120tx_firmware","vendor":"cisco"},{"product":"nexus_93128tx_firmware","vendor":"cisco"},{"product":"nexus_93180yc-ex_firmware","vendor":"cisco"},{"product":"nexus_9332pq_firmware","vendor":"cisco"},{"product":"nexus_9372px_firmware","vendor":"cisco"},{"product":"nexus_9372tx_firmware","vendor":"cisco"},{"product":"nexus_9396px_firmware","vendor":"cisco"},{"product":"nexus_9396tx_firmware","vendor":"cisco"},{"product":"nexus_9500_firmware","vendor":"cisco"},{"product":"nexus_9504_firmware","vendor":"cisco"},{"product":"nexus_9508_firmware","vendor":"cisco"},{"product":"nexus_9516_firmware","vendor":"cisco"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default"},{"id":"CWE-310","name":null}],"description":"A vulnerability in the SSH key management for the Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an unauthenticated, remote attacker to connect to the affected system with the privileges of the root user. The vulnerability is due to the presence of a default SSH key pair that is present in all devices. An attacker could exploit this vulnerability by opening an SSH connection via IPv6 to a targeted device using the extracted key materials.
