An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-0342 exists.\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-2022-0342/ (Markdown: https://insights.sbomify.com/CVE-2022-0342/index.md)","id":"CVE-2022-0342","markdown":"https://insights.sbomify.com/CVE-2022-0342/index.md","name":"CVE-2022-0342","record":{"aliases":["GHSA-5g3j-g6gx-xfcg"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Zyxel firewall firmware","requires_auth":"none","summary":"Attackers can bypass web authentication in Zyxel firewall firmware to gain administrative access to the device.","user_interaction":"not_required","vuln_class":"auth_bypass"},"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":"nsg300_firmware","vendor":"zyxel"},{"product":"usg40_firmware","vendor":"zyxel"},{"product":"usg40w_firmware","vendor":"zyxel"},{"product":"usg60_firmware","vendor":"zyxel"},{"product":"usg60w_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_700_firmware","vendor":"zyxel"},{"product":"vpn1000_firmware","vendor":"zyxel"},{"product":"vpn100_firmware","vendor":"zyxel"},{"product":"vpn300_firmware","vendor":"zyxel"},{"product":"vpn50_firmware","vendor":"zyxel"},{"product":"zywall_1100_firmware","vendor":"zyxel"},{"product":"zywall_110_firmware","vendor":"zyxel"},{"product":"zywall_310_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-287","name":"Improper Authentication"}],"description":"An authentication bypass vulnerability in the CGI program of Zyxel USG/ZyWALL series firmware versions 4.20 through 4.70, USG FLEX series firmware versions 4.50 through 5.20, ATP series firmware versions 4.32 through 5.20, VPN series firmware versions 4.30 through 5.20, and NSG series firmware versions V1.20 through V1.33 Patch 4, which could allow an attacker to bypass the web authentication and obtain administrative access of the device.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":1,"refs":[{"date":null,"kind":"nuclei","ref":"http/cves/2022/CVE-2022-0342.yaml","stars":null,"title":"Zyxel -
