Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2024-20420 in the wild and no public exploit code.\n\nAffected product: Cisco Analog Telephone Adaptor (ATA) 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-2024-20420/ (Markdown: https://insights.sbomify.com/CVE-2024-20420/index.md)","id":"CVE-2024-20420","markdown":"https://insights.sbomify.com/CVE-2024-20420/index.md","name":"CVE-2024-20420","record":{"aliases":["GHSA-w5cm-m7c3-4jj4"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco ATA firmware","requires_auth":"low_privilege","summary":"Authenticated low-privilege attackers can escalate to Admin privileges and execute commands via the web interface due to incorrect authorization checks.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"ata_191_firmware","vendor":"cisco"},{"product":"ata_192_firmware","vendor":"cisco"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-250","name":"Execution with Unnecessary Privileges"}],"description":"A vulnerability in the web-based management interface of Cisco ATA 190 Series Analog Telephone Adapter firmware could allow an authenticated, remote attacker with low privileges to run commands as an Admin user. \r\n\r\nThis vulnerability is due to incorrect authorization verification by the HTTP server.
