An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-20209 exists.\n\nAffected product: Cisco TelePresence Video Communication Server (VCS) Expressway. 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-2023-20209/ (Markdown: https://insights.sbomify.com/CVE-2023-20209/index.md)","id":"CVE-2023-20209","markdown":"https://insights.sbomify.com/CVE-2023-20209/index.md","name":"CVE-2023-20209","record":{"aliases":["GHSA-fqmx-hq6j-36x9"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Expressway VCS","requires_auth":"high_privilege","summary":"Authenticated attackers can execute arbitrary commands with root privileges via the web management interface of Cisco Expressway and VCS devices.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"telepresence_video_communication_server","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"},{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"A vulnerability in the web-based management interface of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker with read-write privileges on the application to perform a command injection attack that could result in remote code execution on an affected device.\r\n\r This vulnerability is due to insufficient validation of user-supplied input.
