Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-1267 in the wild and no public exploit code.\n\nAffected product: Cisco Secure Firewall Management Center. 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-2021-1267/ (Markdown: https://insights.sbomify.com/CVE-2021-1267/index.md)","id":"CVE-2021-1267","markdown":"https://insights.sbomify.com/CVE-2021-1267/index.md","name":"CVE-2021-1267","record":{"aliases":["GHSA-5j3f-6x5j-rrv5"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Firepower Management Center","requires_auth":"low_privilege","summary":"An authenticated attacker can cause a denial of service on Cisco Firepower Management Center by exploiting an XML entity expansion vulnerability in dashboard widgets.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"secure_firewall_management_center","vendor":"cisco"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","version":"3.0"},"cwes":[{"id":"CWE-776","name":"Improper Restriction of Recursive Entity References in DTDs"}],"description":"A vulnerability in the dashboard widget of Cisco Firepower Management Center (FMC) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
