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-2019-18257 in the wild and no public exploit code.\n\nAffected product: Advantech DiagAnywhere Server. 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-2019-18257/ (Markdown: https://insights.sbomify.com/CVE-2019-18257/index.md)","id":"CVE-2019-18257","markdown":"https://insights.sbomify.com/CVE-2019-18257/index.md","name":"CVE-2019-18257","record":{"aliases":["GHSA-mcw9-h8ch-w6m4"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Advantech DiagAnywhere Server","requires_auth":"none","summary":"Unauthenticated attackers can execute arbitrary code via stack-based buffer overflows in the file transfer service of Advantech DiagAnywhere Server.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"diaganywhere","vendor":"advantech"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"In Advantech DiagAnywhere Server, Versions 3.07.11 and prior, multiple stack-based buffer overflow vulnerabilities exist in the file transfer service listening on the TCP port.
