It can only be exploited from the same machine or local network, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2022-45440 and fix it if it is affected.\n\nWhat it is: CVE-2022-45440 is a medium-severity path traversal vulnerability in Zyxel AX7501-B0 firmware, published on 17 Jan 2023. It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-45440 in the wild and no public exploit code.\n\nAffected product: Zyxel AX7501-B0 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-2022-45440/ (Markdown: https://insights.sbomify.com/CVE-2022-45440/index.md)","id":"CVE-2022-45440","markdown":"https://insights.sbomify.com/CVE-2022-45440/index.md","name":"CVE-2022-45440","record":{"aliases":["GHSA-rpwq-xw4m-459x"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Zyxel router firmware","requires_auth":"high_privilege","summary":"A local administrator can access the root file system via symbolic links on external storage in the Zyxel AX7501-B0 FTP server.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"ax7501-b0_firmware","vendor":"zyxel"}],"cvss":{"score":4.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"A vulnerability exists in the FTP server of the Zyxel AX7501-B0 firmware prior to V5.17(ABPC.3)C0, which processes symbolic links on external storage media.
