An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2023-22916 and fix it if it is affected.\n\nWhat it is: CVE-2023-22916 is a high-severity vulnerability in Zyxel ATP series firmware, published on 24 Apr 2023. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2023-22916 in the wild and no public exploit code.\n\nAffected product: Zyxel ATP series 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-2023-22916/ (Markdown: https://insights.sbomify.com/CVE-2023-22916/index.md)","id":"CVE-2023-22916","markdown":"https://insights.sbomify.com/CVE-2023-22916/index.md","name":"CVE-2023-22916","record":{"aliases":["GHSA-34w5-49cc-qp8r"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","data_modify"],"network_reachable":"yes","non_default_config":true,"product_category":"Zyxel firewall firmware","requires_auth":"none","summary":"Remote attackers can cause denial of service by modifying configuration data if an administrator switches to cloud mode.","user_interaction":"required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zyxel","cpe":[{"product":"atp100_firmware","vendor":"zyxel"},{"product":"atp100w_firmware","vendor":"zyxel"},{"product":"atp200_firmware","vendor":"zyxel"},{"product":"atp500_firmware","vendor":"zyxel"},{"product":"atp700_firmware","vendor":"zyxel"},{"product":"atp800_firmware","vendor":"zyxel"},{"product":"usg_20w-vpn_firmware","vendor":"zyxel"},{"product":"usg_flex_100_firmware","vendor":"zyxel"},{"product":"usg_flex_100w_firmware","vendor":"zyxel"},{"product":"usg_flex_200_firmware","vendor":"zyxel"},{"product":"usg_flex_500_firmware","vendor":"zyxel"},{"product":"usg_flex_50_firmware","vendor":"zyxel"},{"product":"usg_flex_50w_firmware","vendor":"zyxel"},{"product":"usg_flex_700_firmware","vendor":"zyxel"},{"product":"vpn1000_firmware","vendor":"zyxel"},{"product":"vpn100_firmware","vendor":"zyxel"},{"product":"vpn300_firmware","vendor":"zyxel"},{"product":"vpn50_firmware","vendor":"zyxel"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"The configuration parser of Zyxel ATP series firmware versions 5.10 through 5.35, USG FLEX series firmware versions 5.00 through 5.35, USG FLEX 50(W) firmware versions 5.10 through 5.35, USG20(W)-VPN firmware versions 5.10 through 5.35, and VPN series firmware versions 5.00 through 5.35, which fails to properly sanitize user input.
