Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-3400 in the wild and no public exploit code.\n\nAffected product: Cisco Ios Xe. 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-2020-3400/ (Markdown: https://insights.sbomify.com/CVE-2020-3400/index.md)","id":"CVE-2020-3400","markdown":"https://insights.sbomify.com/CVE-2020-3400/index.md","name":"CVE-2020-3400","record":{"aliases":["GHSA-wpmp-jhx9-xgq5"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IOS XE","requires_auth":"low_privilege","summary":"An authenticated attacker can bypass web UI authorization checks to perform administrative actions, requiring a patch for Cisco IOS XE.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ios_xe","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A vulnerability in the web UI feature of Cisco IOS XE Software could allow an authenticated, remote attacker to utilize parts of the web UI for which they are not authorized.The vulnerability is due to insufficient authorization of web UI access requests.
