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-2019-1917 in the wild and no public exploit code.\n\nAffected product: Cisco Vision Dynamic Signage 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-2019-1917/ (Markdown: https://insights.sbomify.com/CVE-2019-1917/index.md)","id":"CVE-2019-1917","markdown":"https://insights.sbomify.com/CVE-2019-1917/index.md","name":"CVE-2019-1917","record":{"aliases":["GHSA-q69m-6hqq-2968"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Vision Signage Director","requires_auth":"none","summary":"Unauthenticated remote attackers can bypass authentication to execute arbitrary actions with administrative privileges via the REST API.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"vision_dynamic_signage_director","vendor":"cisco"}],"cvss":{"score":9.1,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"A vulnerability in the REST API interface of Cisco Vision Dynamic Signage Director could allow an unauthenticated, remote attacker to bypass authentication on an affected system.
