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-2025-20354 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-2025-20354/ (Markdown: https://insights.sbomify.com/CVE-2025-20354/index.md)","id":"CVE-2025-20354","markdown":"https://insights.sbomify.com/CVE-2025-20354/index.md","name":"CVE-2025-20354","record":{"aliases":["GHSA-px5r-4v6x-q5mv"],"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 upload files via Java RMI to execute arbitrary commands with root privileges on Cisco Unified CCX systems.","user_interaction":"not_required","vuln_class":"file_upload"},"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:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"A vulnerability in the Java Remote Method Invocation (RMI) process of Cisco Unified CCX could allow an unauthenticated, remote attacker to upload arbitrary files and execute arbitrary commands with root permissions on an affected system.\r\n\r\nThis vulnerability is due to improper authentication mechanisms that are associated to specific Cisco Unified CCX features.
