An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2022-20853 and fix it if it is affected.\n\nWhat it is: CVE-2022-20853 is a high-severity vulnerability in Cisco TelePresence Video Communication Server (VCS) Expressway, published on 15 Nov 2024. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2022-20853 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-2022-20853/ (Markdown: https://insights.sbomify.com/CVE-2022-20853/index.md)","id":"CVE-2022-20853","markdown":"https://insights.sbomify.com/CVE-2022-20853/index.md","name":"CVE-2022-20853","record":{"aliases":["GHSA-pg6h-m56f-q74p"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Expressway","requires_auth":"none","summary":"An unauthenticated attacker can force a system reload via CSRF by tricking a user into clicking a crafted link.","user_interaction":"required","vuln_class":"csrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"telepresence_video_communication_server","vendor":"cisco"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-352","name":"Cross-Site Request Forgery"}],"description":"A vulnerability in the REST API of Cisco\u0026nbsp;Expressway Series and Cisco\u0026nbsp;TelePresence VCS could allow an unauthenticated, remote attacker to conduct a cross-site request forgery (CSRF) attack on an affected system.\r\n\r\nThis vulnerability is due to insufficient CSRF protections for the web-based management interface of an affected system.
