An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2017-16727 and fix it if it is affected.\n\nWhat it is: CVE-2017-16727 is a critical vulnerability in Moxa NPort W2150A and W2250A, published on 22 Dec 2017. 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-2017-16727 in the wild and no public exploit code.\n\nAffected product: Moxa NPort W2150A and W2250A. 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-2017-16727/ (Markdown: https://insights.sbomify.com/CVE-2017-16727/index.md)","id":"CVE-2017-16727","markdown":"https://insights.sbomify.com/CVE-2017-16727/index.md","name":"CVE-2017-16727","record":{"aliases":["GHSA-8vv3-5rrp-vm83"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Moxa NPort serial server","requires_auth":"none","summary":"An attacker can access the device without a password due to an empty default credential, compromising wireless traffic confidentiality and integrity.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"nport_w2150a_firmware","vendor":"moxa"},{"product":"nport_w2250a_firmware","vendor":"moxa"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","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-521","name":"Weak Password Requirements"},{"id":"CWE-255","name":null}],"description":"A Credentials Management issue was discovered in Moxa NPort W2150A versions prior to 1.11, and NPort W2250A versions prior to 1.11.
