It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42543 in the wild and no public exploit code.\n\nAffected product: AzeoTech DAQFactory. 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-2021-42543/ (Markdown: https://insights.sbomify.com/CVE-2021-42543/index.md)","id":"CVE-2021-42543","markdown":"https://insights.sbomify.com/CVE-2021-42543/index.md","name":"CVE-2021-42543","record":{"aliases":["GHSA-7gpm-f37j-r77g"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Industrial SCADA software","requires_auth":"none","summary":"Attackers can execute arbitrary code or cause system shutdown via crafted project files in AzeoTech DAQFactory.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"daqfactory","vendor":"azeotech"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-242","name":"Use of Inherently Dangerous Function"}],"description":"The affected application uses specific functions that could be abused through a crafted project file, which could lead to code execution, system reboot, and system shutdown.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"AzeoTech DAQFactory","id":"CVE-2021-42543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Lack of Rate limiting in Authentication in TopEase","id":"CVE-2021-42544"},"packages":[],"prev":{"headline":"Emerson WirelessHART Gateway","id":"CVE-2021-42542"},"products":["DAQFactory"],"published":"2021-11-05","related":[{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2011-3492","kev_date_added":null,"published":"2011-09-16"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2009-4480","kev_date_added":null,"published":"2009-12-30"},{"cvss_score":8.4,"headline":"Use after free in AzeoTech DAQFactory","id":"CVE-2026-12921","kev_date_added":null,"published":"2026-06-25"},{"cvss_score":8.4,"headline":"Access of resource using incompatible type ('type confusion') in AzeoTech DAQFactory","id":"CVE-2026-12390","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":8.4,"headline":"Access of Uninitialized Pointer vulnerability in AzeoTech DAQFactory","id":"CVE-2025-66588","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":8.4,"headline":"Out-of-bounds Read vulnerability in AzeoTech DAQFactory","id":"CVE-2025-66589","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":8.4,"headline":"Out-of-bounds Write vulnerability in AzeoTech DAQFactory","id":"CVE-2025-66590","kev_date_added":null,"published":"2025-12-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["AzeoTech"]},"summary":"Attackers can execute arbitrary code or cause system shutdown via crafted project files in AzeoTech DAQFactory.","url":"https://insights.sbomify.com/CVE-2021-42543/"}
