It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-1684 in the wild and no public exploit code.\n\nAffected product: Cisco IP Phone 8800 Series Software. 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-2019-1684/ (Markdown: https://insights.sbomify.com/CVE-2019-1684/index.md)","id":"CVE-2019-1684","markdown":"https://insights.sbomify.com/CVE-2019-1684/index.md","name":"CVE-2019-1684","record":{"aliases":["GHSA-325p-cm4c-j6f9"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IP Phone","requires_auth":"none","summary":"An adjacent attacker can cause a temporary denial of service on Cisco IP phones by sending malicious CDP or LLDP packets.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ip_conference_phone_7832_firmware","vendor":"cisco"},{"product":"ip_conference_phone_8832_firmware","vendor":"cisco"},{"product":"ip_phone_7800_firmware","vendor":"cisco"},{"product":"ip_phone_7811_firmware","vendor":"cisco"},{"product":"ip_phone_7821_firmware","vendor":"cisco"},{"product":"ip_phone_7841_firmware","vendor":"cisco"},{"product":"ip_phone_7861_firmware","vendor":"cisco"},{"product":"ip_phone_8800_firmware","vendor":"cisco"},{"product":"ip_phone_8811_firmware","vendor":"cisco"},{"product":"ip_phone_8841_firmware","vendor":"cisco"},{"product":"ip_phone_8845_firmware","vendor":"cisco"},{"product":"ip_phone_8851_firmware","vendor":"cisco"},{"product":"ip_phone_8861_firmware","vendor":"cisco"},{"product":"ip_phone_8865_firmware","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-399","name":null}],"description":"A vulnerability in the Cisco Discovery Protocol or Link Layer Discovery Protocol (LLDP) implementation for the Cisco IP Phone 7800 and 8800 Series could allow an unauthenticated, adjacent attacker to cause an affected phone to reload unexpectedly, resulting in a temporary denial of service (DoS) condition. The vulnerability is due to missing length validation of certain Cisco Discovery Protocol or LLDP packet header fields. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol or LLDP packet to the targeted phone. A successful exploit could allow the attacker to cause the affected phone to reload unexpectedly, resulting in a temporary DoS condition.
