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-2021-34711 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-2021-34711/ (Markdown: https://insights.sbomify.com/CVE-2021-34711/index.md)","id":"CVE-2021-34711","markdown":"https://insights.sbomify.com/CVE-2021-34711/index.md","name":"CVE-2021-34711","record":{"aliases":["GHSA-rh9c-8fw7-2j3p"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Cisco IP Phone","requires_auth":"low_privilege","summary":"An authenticated local attacker can read arbitrary files on Cisco IP Phones via insufficient input validation in the debug shell.","user_interaction":"not_required","vuln_class":"path_traversal"},"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_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_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"},{"product":"ip_phones_8832_firmware","vendor":"cisco"},{"product":"wireless_ip_phone_8821_firmware","vendor":"cisco"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"},{"id":"CWE-36","name":"Absolute Path Traversal"}],"description":"A vulnerability in the debug shell of Cisco IP Phone software could allow an authenticated, local attacker to read any file on the device file system.
