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-2024-20451 in the wild and no public exploit code.\n\nAffected product: Cisco Small Business IP Phones. 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-2024-20451/ (Markdown: https://insights.sbomify.com/CVE-2024-20451/index.md)","id":"CVE-2024-20451","markdown":"https://insights.sbomify.com/CVE-2024-20451/index.md","name":"CVE-2024-20451","record":{"aliases":["GHSA-3gj8-mpqg-gqrv"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cisco IP Phones","requires_auth":"none","summary":"Unauthenticated remote attackers can cause Cisco Small Business IP Phones to reload unexpectedly by sending crafted HTTP packets, resulting in a denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"spa_301_firmware","vendor":"cisco"},{"product":"spa_303_firmware","vendor":"cisco"},{"product":"spa_501g_firmware","vendor":"cisco"},{"product":"spa_502g_firmware","vendor":"cisco"},{"product":"spa_504g_firmware","vendor":"cisco"},{"product":"spa_508g_firmware","vendor":"cisco"},{"product":"spa_509g_firmware","vendor":"cisco"},{"product":"spa_512g_firmware","vendor":"cisco"},{"product":"spa_514g_firmware","vendor":"cisco"},{"product":"spa_525g2_firmware","vendor":"cisco"},{"product":"spa_525g_firmware","vendor":"cisco"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"Multiple vulnerabilities in the web-based management interface of Cisco Small Business SPA300 Series IP Phones and Cisco Small Business SPA500 Series IP Phones could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly.\r\n\r\nThese vulnerabilities exist because HTTP packets are not properly checked for errors.
