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-2020-3456 and fix it if it is affected.\n\nWhat it is: CVE-2020-3456 is a high-severity vulnerability in Cisco Firepower Extensible Operating System, published on 21 Oct 2020. 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-2020-3456 in the wild and no public exploit code.\n\nAffected product: Cisco Firepower Extensible Operating System. 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-2020-3456/ (Markdown: https://insights.sbomify.com/CVE-2020-3456/index.md)","id":"CVE-2020-3456","markdown":"https://insights.sbomify.com/CVE-2020-3456/index.md","name":"CVE-2020-3456","record":{"aliases":["GHSA-327p-j9g4-qf3q"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco FXOS Chassis Manager","requires_auth":"none","summary":"An unauthenticated remote attacker can perform unauthorized actions on behalf of a user via CSRF in Cisco FXOS Firepower Chassis Manager.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"firepower_extensible_operating_system","vendor":"cisco"}],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A vulnerability in the Cisco Firepower Chassis Manager (FCM) of Cisco FXOS Software could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack against a user of an affected device.
