An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-20817 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-2022-20817/ (Markdown: https://insights.sbomify.com/CVE-2022-20817/index.md)","id":"CVE-2022-20817","markdown":"https://insights.sbomify.com/CVE-2022-20817/index.md","name":"CVE-2022-20817","record":{"aliases":["GHSA-83p3-3frh-4fjj"],"analysis":{"component_type":"iot_embedded","fix_type":"workaround","impacts":["security_bypass","other"],"network_reachable":"yes","non_default_config":true,"product_category":"Cisco IP Phone","requires_auth":"none","summary":"An attacker can impersonate a user's phone via machine-in-the-middle attacks due to duplicate cryptographic keys generated during manufacturing.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ata_187_analog_telephone_adapter_firmware","vendor":"cisco"},{"product":"unified_ip_phone_6911_firmware","vendor":"cisco"},{"product":"unified_ip_phone_6921_firmware","vendor":"cisco"},{"product":"unified_ip_phone_6941_firmware","vendor":"cisco"},{"product":"unified_ip_phone_6945_firmware","vendor":"cisco"},{"product":"unified_ip_phone_6961_firmware","vendor":"cisco"},{"product":"unified_ip_phone_8941_firmware","vendor":"cisco"},{"product":"unified_ip_phone_8945_firmware","vendor":"cisco"},{"product":"unified_ip_phone_8961_firmware","vendor":"cisco"},{"product":"unified_ip_phone_9951_firmware","vendor":"cisco"},{"product":"unified_ip_phone_9971_firmware","vendor":"cisco"}],"cvss":{"score":7.4,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-338","name":"Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)"}],"description":"A vulnerability in Cisco Unified IP Phones could allow an unauthenticated, remote attacker to impersonate another user's phone if the Cisco Unified Communications Manager (CUCM) is in secure mode. This vulnerability is due to improper key generation during the manufacturing process that could result in duplicated manufactured keys installed on multiple devices. An attacker could exploit this vulnerability by performing a machine-in-the-middle attack on the secure communication between the phone and the CUCM. A successful exploit could allow the attacker to impersonate another user's phone. This vulnerability cannot be addressed with software updates.
