An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2023-22920 and fix it if it is affected.\n\nWhat it is: CVE-2023-22920 is a critical vulnerability in Zyxel LTE3316-M604, published on 21 Feb 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-2023-22920 in the wild and no public exploit code.\n\nAffected product: Zyxel LTE3316-M604. 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-2023-22920/ (Markdown: https://insights.sbomify.com/CVE-2023-22920/index.md)","id":"CVE-2023-22920","markdown":"https://insights.sbomify.com/CVE-2023-22920/index.md","name":"CVE-2023-22920","record":{"aliases":["GHSA-wpqc-593w-375g"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"LTE router","requires_auth":"none","summary":"A remote attacker can access the Zyxel LTE3316-M604 router via Telnet due to a factory default testing misconfiguration.","user_interaction":"not_required","vuln_class":"misconfiguration"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"lte3202-m437_firmware","vendor":"zyxel"},{"product":"lte3316-m604_firmware","vendor":"zyxel"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"A security misconfiguration vulnerability exists in the Zyxel LTE3316-M604 firmware version V2.00(ABMP.6)C0 due to a factory default misconfiguration intended for testing purposes.
