It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-42706 and fix it if it is affected.\n\nWhat it is: CVE-2021-42706 is a high-severity use after free vulnerability in Advantech HMI Designer, published on 15 Nov 2021. 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-2021-42706 in the wild and no public exploit code.\n\nAffected product: Advantech HMI Designer. 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-2021-42706/ (Markdown: https://insights.sbomify.com/CVE-2021-42706/index.md)","id":"CVE-2021-42706","markdown":"https://insights.sbomify.com/CVE-2021-42706/index.md","name":"CVE-2021-42706","record":{"aliases":["GHSA-73jf-94cc-m479"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"HMI Designer","requires_auth":"none","summary":"An attacker can exploit a use-after-free flaw in Advantech HMI Designer to disclose information and execute arbitrary code.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess_hmi_designer","vendor":"advantech"}],"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-416","name":"Use After Free"}],"description":"This vulnerability could allow an attacker to disclose information and execute arbitrary code on affected installations of WebAccess/MHI Designer","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-2021-42706","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"WECON PLC Editor","id":"CVE-2021-42707"},"packages":[],"prev":{"headline":"WECON PLC Editor","id":"CVE-2021-42705"},"products":["HMI Designer"],"published":"2021-11-15","related":[{"cvss_score":8.8,"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2019-10961","kev_date_added":null,"published":"2019-08-02"},{"cvss_score":7.8,"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2018-8833","kev_date_added":null,"published":"2018-04-25"},{"cvss_score":7.8,"headline":"Use after free in Advantech WebAccess HMI Designer","id":"CVE-2018-8835","kev_date_added":null,"published":"2018-04-25"},{"cvss_score":7.8,"headline":"Memory corruption in Advantech WebAccess HMI Designer","id":"CVE-2018-8837","kev_date_added":null,"published":"2018-04-25"},{"cvss_score":5.4,"headline":"AzeoTech DAQFactory","id":"CVE-2021-42703","kev_date_added":null,"published":"2021-11-15"}],"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":"2024-09-16","vendors":["Advantech"]},"summary":"An attacker can exploit a use-after-free flaw in Advantech HMI Designer to disclose information and execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2021-42706/"}
