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-2023-20018 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-2023-20018/ (Markdown: https://insights.sbomify.com/CVE-2023-20018/index.md)","id":"CVE-2023-20018","markdown":"https://insights.sbomify.com/CVE-2023-20018/index.md","name":"CVE-2023-20018","record":{"aliases":["GHSA-jc6w-v2gh-gqx3"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IP Phone","requires_auth":"none","summary":"Unauthenticated remote attackers can bypass authentication on Cisco IP Phones to access restricted parts of the web management interface.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ip_phone_7800_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_8800_firmware","vendor":"cisco"},{"product":"ip_phone_8811_firmware","vendor":"cisco"},{"product":"ip_phone_8821-ex_firmware","vendor":"cisco"},{"product":"ip_phone_8821_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"},{"product":"ip_phones_8832_firmware","vendor":"cisco"},{"product":"unified_ip_phone_8851nr_firmware","vendor":"cisco"},{"product":"unified_ip_phone_8865nr_firmware","vendor":"cisco"},{"product":"wireless_ip_phone_8821-ex_firmware","vendor":"cisco"},{"product":"wireless_ip_phone_8821_firmware","vendor":"cisco"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-288","name":"Authentication Bypass Using an Alternate Path or Channel"}],"description":"A vulnerability in the web-based management interface of Cisco IP Phone 7800 and 8800 Series Phones could allow an unauthenticated, remote attacker to bypass authentication on an affected device.\r\n\r This vulnerability is due to insufficient validation of user-supplied input.
