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-2020-3280 in the wild and no public exploit code.\n\nAffected product: Cisco Unified Contact Center Express. 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-2020-3280/ (Markdown: https://insights.sbomify.com/CVE-2020-3280/index.md)","id":"CVE-2020-3280","markdown":"https://insights.sbomify.com/CVE-2020-3280/index.md","name":"CVE-2020-3280","record":{"aliases":["GHSA-7qv8-fcr4-9523"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unified CCX","requires_auth":"none","summary":"Unauthenticated remote attackers can execute arbitrary code as root via insecure Java deserialization in Cisco Unified Contact Center Express.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unified_contact_center_express","vendor":"cisco"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Java Remote Management Interface of Cisco Unified Contact Center Express (Unified CCX) could allow an unauthenticated, remote attacker to execute arbitrary code on an affected device.
