Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-42540 and fix it if it is affected.\n\nWhat it is: CVE-2021-42540 is a high-severity path traversal vulnerability in Emerson WirelessHART Gateway, published on 22 Oct 2021. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42540 in the wild and no public exploit code.\n\nAffected product: Emerson WirelessHART Gateway. 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-2021-42540/ (Markdown: https://insights.sbomify.com/CVE-2021-42540/index.md)","id":"CVE-2021-42540","markdown":"https://insights.sbomify.com/CVE-2021-42540/index.md","name":"CVE-2021-42540","record":{"aliases":["GHSA-2gp7-jhh8-9gqw"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["data_modify","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"WirelessHART Gateway","requires_auth":"low_privilege","summary":"A low-privileged user can exploit unsanitized folder extraction to overwrite system settings and key functionality in the Emerson WirelessHART Gateway.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"wireless_1410_gateway_firmware","vendor":"emerson"},{"product":"wireless_1410d_gateway_firmware","vendor":"emerson"},{"product":"wireless_1420_gateway_firmware","vendor":"emerson"}],"cvss":{"score":8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-123","name":"Write-what-where Condition"}],"description":"The affected product is vulnerable to a unsanitized extract folder for system configuration.
