An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-1748 and fix it if it is affected.\n\nWhat it is: CVE-2023-1748 is a critical vulnerability in Nexx Garage Door Controller NXG-100B, NXG-200, published on 4 Apr 2023. 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-2023-1748 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-2023-1748/ (Markdown: https://insights.sbomify.com/CVE-2023-1748/index.md)","id":"CVE-2023-1748","markdown":"https://insights.sbomify.com/CVE-2023-1748/index.md","name":"CVE-2023-1748","record":{"aliases":["GHSA-jj5g-444x-7r89"],"analysis":{"component_type":"iot_embedded","fix_type":"no_fix_stated","impacts":["account_takeover","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Nexx Smart Home devices","requires_auth":"none","summary":"Hardcoded credentials in Nexx Smart Home devices allow unauthenticated attackers to access MQTT servers and remotely control garage doors or smart plugs.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"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":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-798","name":"Use of Hard-coded Credentials"}],"description":"The listed versions of Nexx Smart Home devices use hard-coded credentials.
