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-2020-28899 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-28899/ (Markdown: https://insights.sbomify.com/CVE-2020-28899/index.md)","id":"CVE-2020-28899","markdown":"https://insights.sbomify.com/CVE-2020-28899/index.md","name":"CVE-2020-28899","record":{"aliases":["GHSA-345j-gpg7-fhmx"],"analysis":{"component_type":"network_device","fix_type":"no_fix_stated","impacts":["privilege_escalation","data_read","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"LTE router","requires_auth":"none","summary":"Remote attackers can access all router features without authentication, allowing password changes, Wi-Fi key retrieval, and internal network access.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"lte4506-m606_firmware","vendor":"zyxel"},{"product":"lte7460-m608_firmware","vendor":"zyxel"},{"product":"wah7706_firmware","vendor":"zyxel"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"The Web CGI Script on ZyXEL LTE4506-M606 V1.00(ABDO.2)C0 devices does not require authentication, which allows remote unauthenticated attackers (via crafted JSON action data to /cgi-bin/gui.cgi) to use all features provided by the router.
