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-2019-1848 in the wild and no public exploit code.\n\nAffected product: Cisco Digital Network Architecture Center (DNA Center). 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-2019-1848/ (Markdown: https://insights.sbomify.com/CVE-2019-1848/index.md)","id":"CVE-2019-1848","markdown":"https://insights.sbomify.com/CVE-2019-1848/index.md","name":"CVE-2019-1848","record":{"aliases":["GHSA-72v5-4c4w-2chj"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco DNA Center","requires_auth":"none","summary":"An unauthenticated adjacent attacker can bypass authentication to access critical internal services by connecting to the cluster services subnet.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"digital_network_architecture_center","vendor":"cisco"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-668","name":"Exposure of Resource to Wrong Sphere"}],"description":"A vulnerability in Cisco Digital Network Architecture (DNA) Center could allow an unauthenticated, adjacent attacker to bypass authentication and access critical internal services.
