An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-3616 and fix it if it is affected.\n\nWhat it is: CVE-2021-3616 is a critical missing authorization vulnerability in Lenovo Smart Camera X3, X5, and C2E firmware, published on 17 Aug 2021. 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-2021-3616 in the wild and no public exploit code.\n\nAffected product: Lenovo Smart Camera X3, X5, and C2E firmware. 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-2021-3616/ (Markdown: https://insights.sbomify.com/CVE-2021-3616/index.md)","id":"CVE-2021-3616","markdown":"https://insights.sbomify.com/CVE-2021-3616/index.md","name":"CVE-2021-3616","record":{"aliases":["GHSA-qrw6-qjvm-cr2m"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Lenovo Smart Camera","requires_auth":"none","summary":"An unauthorized user can view device information and alter firmware or configuration on Lenovo Smart Cameras due to missing authorization checks.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"lenovo","cpe":[{"product":"smart_camera_c2e_firmware","vendor":"lenovo"},{"product":"smart_camera_x3_firmware","vendor":"lenovo"},{"product":"smart_camera_x5_firmware","vendor":"lenovo"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"A vulnerability was reported in Lenovo Smart Camera X3, X5, and C2E that could allow an unauthorized user to view device information, alter firmware content and device configuration.
