An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-38424 in the wild and no public exploit code.\n\nAffected product: Delta Electronics DIALink. 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-2021-38424/ (Markdown: https://insights.sbomify.com/CVE-2021-38424/index.md)","id":"CVE-2021-38424","markdown":"https://insights.sbomify.com/CVE-2021-38424/index.md","name":"CVE-2021-38424","record":{"aliases":["GHSA-39mq-9cjh-6382"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Delta DIALink","requires_auth":"high_privilege","summary":"Attackers can inject malicious formulas into DIALink tags that execute code when opened in spreadsheet applications, posing a risk to industrial control systems.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"dialink","vendor":"deltaww"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-1236","name":"Improper Neutralization of Formula Elements in a CSV File"}],"description":"The tag interface of Delta Electronics DIALink versions 1.2.4.0 and prior is vulnerable to an attacker injecting formulas into the tag data.
