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-2020-3111 in the wild and no public exploit code.\n\nAffected product: Cisco IP phone. 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-2020-3111/ (Markdown: https://insights.sbomify.com/CVE-2020-3111/index.md)","id":"CVE-2020-3111","markdown":"https://insights.sbomify.com/CVE-2020-3111/index.md","name":"CVE-2020-3111","record":{"aliases":["GHSA-w6xx-2hjv-77cm"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","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 execute arbitrary code with root privileges or cause a denial of service on Cisco IP Phones via crafted CDP 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_firmware","vendor":"cisco"},{"product":"ip_phone_6841_firmware","vendor":"cisco"},{"product":"ip_phone_6851_firmware","vendor":"cisco"},{"product":"ip_phone_6861_firmware","vendor":"cisco"},{"product":"ip_phone_6871_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":"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":8.8,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"A vulnerability in the Cisco Discovery Protocol implementation for the Cisco IP Phone could allow an unauthenticated, adjacent attacker to remotely execute code with root privileges or cause a reload of an affected IP phone. The vulnerability is due to missing checks when processing Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to the targeted IP phone. A successful exploit could allow the attacker to remotely execute code with root privileges or cause a reload of an affected IP phone, resulting in a denial of service (DoS) condition. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Cisco IP Phone Remote Code Execution and Denial of Service Vulnerability","id":"CVE-2020-3111","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":2,"next":{"headline":"Cisco Data Center Network Manager Privilege Escalation Vulnerability","id":"CVE-2020-3112"},"packages":[],"prev":{"headline":"Memory corruption in Cisco Video Surveillance 8000 Series IP Cameras","id":"CVE-2020-3110"},"products":["Cisco IP phone"],"published":"2020-02-05","related":[{"cvss_score":7.5,"headline":"Cisco IP Phone 7800 Series and 8800 Series Session Initiation Protocol XML Denial of Service Vulnerability","id":"CVE-2019-1635","kev_date_added":null,"published":"2019-05-03"},{"cvss_score":6.5,"headline":"Memory corruption in Cisco IP Phones with Multiplatform Firmware","id":"CVE-2021-1379","kev_date_added":null,"published":"2024-11-18"},{"cvss_score":6.5,"headline":"Denial of service in Cisco IP Phone 8800 Series Software","id":"CVE-2019-1684","kev_date_added":null,"published":"2019-02-21"},{"cvss_score":5.5,"headline":"Cisco IP Phone Software Arbitrary File Read Vulnerability","id":"CVE-2021-34711","kev_date_added":null,"published":"2021-10-06"},{"cvss_score":5.3,"headline":"Cisco IP Phone 7800 and 8800 Series Session Initiation Protocol Denial of Service Vulnerability","id":"CVE-2019-1922","kev_date_added":null,"published":"2019-07-06"},{"cvss_score":4.6,"headline":"Cisco IP Phones Information Disclosure Vulnerability","id":"CVE-2022-20660","kev_date_added":null,"published":"2022-01-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-11-15","vendors":["Cisco"]},"summary":"An adjacent attacker can execute arbitrary code with root privileges or cause a denial of service on Cisco IP Phones via crafted CDP packets.","url":"https://insights.sbomify.com/CVE-2020-3111/"}
