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-2021-1379 in the wild and no public exploit code.\n\nAffected product: Cisco IP Phones with Multiplatform Firmware. 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-2021-1379/ (Markdown: https://insights.sbomify.com/CVE-2021-1379/index.md)","id":"CVE-2021-1379","markdown":"https://insights.sbomify.com/CVE-2021-1379/index.md","name":"CVE-2021-1379","record":{"aliases":["GHSA-722m-4rr5-cvfh"],"analysis":{"component_type":"iot_embedded","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IP Phones","requires_auth":"none","summary":"Unauthenticated adjacent attackers can execute code or cause denial of service on Cisco IP Phones via malicious CDP or LLDP packets.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ip_conference_phone_7832_firmware","vendor":"cisco"},{"product":"ip_conference_phone_7832_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_conference_phone_8832_firmware","vendor":"cisco"},{"product":"ip_conference_phone_8832_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_6821_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_6841_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_6851_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_6861_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_6871_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_7811_firmware","vendor":"cisco"},{"product":"ip_phone_7811_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_7821_firmware","vendor":"cisco"},{"product":"ip_phone_7821_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_7841_firmware","vendor":"cisco"},{"product":"ip_phone_7841_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_7861_firmware","vendor":"cisco"},{"product":"ip_phone_7861_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_8811_firmware","vendor":"cisco"},{"product":"ip_phone_8811_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_8841_firmware","vendor":"cisco"},{"product":"ip_phone_8841_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_8845_firmware","vendor":"cisco"},{"product":"ip_phone_8845_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_8851_firmware","vendor":"cisco"},{"product":"ip_phone_8851_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_8861_firmware","vendor":"cisco"},{"product":"ip_phone_8861_with_multiplatform_firmware","vendor":"cisco"},{"product":"ip_phone_8865_firmware","vendor":"cisco"},{"product":"ip_phone_8865_with_multiplatform_firmware","vendor":"cisco"},{"product":"spa525g_firmware","vendor":"cisco"},{"product":"unified_ip_conference_phone_8831_firmware","vendor":"cisco"},{"product":"unified_ip_conference_phone_8831_for_third-party_call_control_firmware","vendor":"cisco"},{"product":"wireless_ip_phone_8821-ex_firmware","vendor":"cisco"},{"product":"wireless_ip_phone_8821_firmware","vendor":"cisco"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/RL:X/RC:X/E:X","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Multiple vulnerabilities in the Cisco\u0026nbsp;Discovery Protocol and Link Layer Discovery Protocol (LLDP) implementations for Cisco\u0026nbsp;IP Phone Series 68xx/78xx/88xx could allow an unauthenticated, adjacent attacker to execute code remotely or cause a reload of an affected IP phone.\r\nThese vulnerabilities are due to missing checks when the IP phone processes a Cisco\u0026nbsp;Discovery Protocol or LLDP packet.
