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-2022-20968 in the wild and no public exploit code.\n\nAffected product: Cisco Session Initiation Protocol (SIP) 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-2022-20968/ (Markdown: https://insights.sbomify.com/CVE-2022-20968/index.md)","id":"CVE-2022-20968","markdown":"https://insights.sbomify.com/CVE-2022-20968/index.md","name":"CVE-2022-20968","record":{"aliases":["GHSA-39vj-2wxm-c37w"],"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 firmware","requires_auth":"none","summary":"An unauthenticated adjacent attacker can cause a stack overflow via crafted CDP packets, leading to remote code execution or denial of service on Cisco IP phones.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ip_phone_7811_firmware","vendor":"cisco"},{"product":"ip_phone_7821_firmware","vendor":"cisco"},{"product":"ip_phone_7832_firmware","vendor":"cisco"},{"product":"ip_phone_7841_firmware","vendor":"cisco"},{"product":"ip_phone_7861_firmware","vendor":"cisco"},{"product":"ip_phone_8811_firmware","vendor":"cisco"},{"product":"ip_phone_8831_firmware","vendor":"cisco"},{"product":"ip_phone_8832_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":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"A vulnerability in the Cisco Discovery Protocol processing feature of Cisco IP Phone 7800 and 8800 Series firmware could allow an unauthenticated, adjacent attacker to cause a stack overflow on an affected device.\r\n\r\nThis vulnerability is due to insufficient input validation of received Cisco Discovery Protocol packets.
