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-2023-1751 in the wild and no public exploit code.\n\nAffected product: Nexx Garage Door Controller NXG-100B, NXG-200. 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-2023-1751/ (Markdown: https://insights.sbomify.com/CVE-2023-1751/index.md)","id":"CVE-2023-1751","markdown":"https://insights.sbomify.com/CVE-2023-1751/index.md","name":"CVE-2023-1751","record":{"aliases":["GHSA-8j4q-8455-qxw3"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Nexx Smart Home devices","requires_auth":"none","summary":"Authorized users can access alarm data from other devices due to missing bearer token validation in the WebSocket server.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"nxal-100_firmware","vendor":"getnexx"},{"product":"nxg-100b_firmware","vendor":"getnexx"},{"product":"nxg-200_firmware","vendor":"getnexx"},{"product":"nxpg-100w_firmware","vendor":"getnexx"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[],"description":"The listed versions of Nexx Smart Home devices use a WebSocket server that does not validate if the bearer token in the Authorization header belongs to the device attempting to associate.
