An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2024-1220 and fix it if it is affected.\n\nWhat it is: CVE-2024-1220 is a high-severity memory corruption vulnerability in Moxa NPort W2150A/W2250A Series, published on 6 Mar 2024. 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-2024-1220 in the wild and no public exploit code.\n\nAffected product: Moxa NPort W2150A/W2250A Series. 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-2024-1220/ (Markdown: https://insights.sbomify.com/CVE-2024-1220/index.md)","id":"CVE-2024-1220","markdown":"https://insights.sbomify.com/CVE-2024-1220/index.md","name":"CVE-2024-1220","record":{"aliases":["GHSA-h7pr-3fcx-999q"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Moxa NPort W2150A","requires_auth":"none","summary":"A remote attacker can cause a denial of service on Moxa NPort W2150A/W2250A devices by sending crafted payloads to the web server.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Moxa","cpe":[{"product":"nport_w2150a-t_firmware","vendor":"moxa"},{"product":"nport_w2150a_firmware","vendor":"moxa"},{"product":"nport_w2250a-t_firmware","vendor":"moxa"},{"product":"nport_w2250a_firmware","vendor":"moxa"}],"cvss":{"score":8.2,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"A stack-based buffer overflow in the built-in web server in Moxa NPort W2150A/W2250A Series firmware version 2.3 and prior allows a remote attacker to exploit the vulnerability by sending crafted payload to the web service.
