An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-20755 in the wild and no public exploit code.\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-2022-20755/ (Markdown: https://insights.sbomify.com/CVE-2022-20755/index.md)","id":"CVE-2022-20755","markdown":"https://insights.sbomify.com/CVE-2022-20755/index.md","name":"CVE-2022-20755","record":{"aliases":["GHSA-r28m-fphr-v4pf"],"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 exploit path traversal to write files and execute arbitrary code as root on Cisco Expressway and VCS devices.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"telepresence_video_communication_server","vendor":"cisco"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-23","name":"Relative Path Traversal"}],"description":"Multiple vulnerabilities in the API and web-based management interfaces of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker with read/write privileges to the application to write files or execute arbitrary code on the underlying operating system of an affected device as the root user.
