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-2025-20358 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-2025-20358/ (Markdown: https://insights.sbomify.com/CVE-2025-20358/index.md)","id":"CVE-2025-20358","markdown":"https://insights.sbomify.com/CVE-2025-20358/index.md","name":"CVE-2025-20358","record":{"aliases":["GHSA-w3hc-3vf9-xjj9"],"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 attackers can bypass authentication to create and execute arbitrary scripts on Cisco Unified CCX servers, leading to code execution.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"unified_contact_center_express","vendor":"cisco"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"A vulnerability in the Contact Center Express (CCX) Editor application of Cisco Unified CCX could allow an unauthenticated, remote attacker to bypass authentication and obtain administrative permissions pertaining to script creation and execution.\r\n\r\nThis vulnerability is due to improper authentication mechanisms in the communication between the CCX Editor and an affected Unified CCX server.
