An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2025-66174 and fix it if it is affected.\n\nWhat it is: CVE-2025-66174 is a medium-severity authentication bypass vulnerability in Hikvision DS-7104HGHI-F1, published on 19 Dec 2025. 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-2025-66174 in the wild and no public exploit code.\n\nAffected product: Hikvision DS-7104HGHI-F1. 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-2025-66174/ (Markdown: https://insights.sbomify.com/CVE-2025-66174/index.md)","id":"CVE-2025-66174","markdown":"https://insights.sbomify.com/CVE-2025-66174/index.md","name":"CVE-2025-66174","record":{"aliases":["GHSA-7h47-c92x-cf8w"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Hikvision DVR","requires_auth":"none","summary":"An attacker with physical access can bypass serial port authentication to execute arbitrary commands on Hikvision DVR devices.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"hikvision","cpe":[{"product":"ds-7104hghi-f1_firmware","vendor":"hikvision"},{"product":"ds-7204hghi-f1_firmware","vendor":"hikvision"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"There is an improper authentication vulnerability in some Hikvision DVR products.
