An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-42703 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-2021-42703/ (Markdown: https://insights.sbomify.com/CVE-2021-42703/index.md)","id":"CVE-2021-42703","markdown":"https://insights.sbomify.com/CVE-2021-42703/index.md","name":"CVE-2021-42703","record":{"aliases":["GHSA-g22f-95g3-fg47"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["account_takeover","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HMI Designer","requires_auth":"none","summary":"An attacker can inject malicious JavaScript to hijack user sessions and redirect users to malicious pages in Advantech HMI Designer.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess_hmi_designer","vendor":"advantech"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"This vulnerability could allow an attacker to send malicious Javascript code resulting in hijacking of the user’s cookie/session tokens, redirecting the user to a malicious webpage, and performing unintended browser action.","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-2021-42703","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Inkscape Out-of-bounds Write","id":"CVE-2021-42704"},"packages":[],"prev":{"headline":"Inkscape Access of Uninitialized Pointer","id":"CVE-2021-42702"},"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":"AzeoTech DAQFactory","id":"CVE-2021-42706","kev_date_added":null,"published":"2021-11-15"},{"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"}],"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":"2024-09-17","vendors":["Advantech"]},"summary":"An attacker can inject malicious JavaScript to hijack user sessions and redirect users to malicious pages in Advantech HMI Designer.","url":"https://insights.sbomify.com/CVE-2021-42703/"}
