TelePresence Video Communication Server (VCS) and Expressway, published on 15 Aug 2018. 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-2018-0409 in the wild and no public exploit code.\n\nAffected product: Cisco Systems, Inc. TelePresence Video Communication Server (VCS) and 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-2018-0409/ (Markdown: https://insights.sbomify.com/CVE-2018-0409/index.md)","id":"CVE-2018-0409","markdown":"https://insights.sbomify.com/CVE-2018-0409/index.md","name":"CVE-2018-0409","record":{"aliases":["GHSA-qqxj-4rg7-qpmv"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco Unified Communications","requires_auth":"none","summary":"An unauthenticated remote attacker can cause a denial of service in Cisco Unified Communications Manager IM\u0026P and TelePresence VCS by sending malicious packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"telepresence_video_communication_server","vendor":"cisco"},{"product":"unified_communications_manager_im_and_presence_service","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the XCP Router service of the Cisco Unified Communications Manager IM \u0026 Presence Service (CUCM IM\u0026P) and the Cisco TelePresence Video Communication Server (VCS) and Expressway could allow an unauthenticated, remote attacker to cause a temporary service outage for all IM\u0026P users, resulting in a denial of service (DoS) condition. The vulnerability is due to improper validation of user-supplied input. An attacker could exploit this vulnerability by sending a malicious IPv4 or IPv6 packet to an affected device on TCP port 7400. An exploit could allow the attacker to overread a buffer, resulting in a crash and restart of the XCP Router service.
