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-2019-1974 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Computing System Director. 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-2019-1974/ (Markdown: https://insights.sbomify.com/CVE-2019-1974/index.md)","id":"CVE-2019-1974","markdown":"https://insights.sbomify.com/CVE-2019-1974/index.md","name":"CVE-2019-1974","record":{"aliases":["GHSA-gxx4-r6p9-84cg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco UCS Director","requires_auth":"none","summary":"Unauthenticated remote attackers can bypass authentication to gain full administrative access to Cisco IMC Supervisor and UCS Director systems.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"integrated_management_controller_supervisor","vendor":"cisco"},{"product":"ucs_director","vendor":"cisco"},{"product":"ucs_director_express_for_big_data","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-287","name":"Improper Authentication"}],"description":"A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow an unauthenticated, remote attacker to bypass user authentication and gain access as an administrative user.
