Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-4203 exists.\n\nAffected product: Advantech EKI-1521. 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-2023-4203/ (Markdown: https://insights.sbomify.com/CVE-2023-4203/index.md)","id":"CVE-2023-4203","markdown":"https://insights.sbomify.com/CVE-2023-4203/index.md","name":"CVE-2023-4203","record":{"aliases":["GHSA-mfq6-hv3w-q46x"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Advantech industrial gateway","requires_auth":"low_privilege","summary":"Authenticated users can inject malicious scripts via the ping tool in Advantech EKI-152x devices, potentially compromising other users.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CyberDanube","cpe":[{"product":"eki-1521_firmware","vendor":"advantech"},{"product":"eki-1522_firmware","vendor":"advantech"},{"product":"eki-1524_firmware","vendor":"advantech"}],"cvss":{"score":9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Advantech EKI-1524, EKI-1522, EKI-1521 devices through 1.21 are affected by a Stored Cross-Site Scripting vulnerability, which can be triggered by authenticated users in the ping tool of the web-interface.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Stored Cross-Site Scripting","id":"CVE-2023-4203","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"NPort IAW5000A-I/O Series Hardcoded Credential Vulnerability","id":"CVE-2023-4204"},"packages":[],"prev":{"headline":"Stored Cross-Site Scripting","id":"CVE-2023-4202"},"products":["EKI-1521","EKI-1522","EKI-1524"],"published":"2023-08-08","related":[{"cvss_score":9,"headline":"Stored Cross-Site Scripting","id":"CVE-2023-4202","kev_date_added":null,"published":"2023-08-08"},{"cvss_score":8.8,"headline":"Authenticated Command Injection","id":"CVE-2023-2573","kev_date_added":null,"published":"2023-05-08"},{"cvss_score":8.8,"headline":"Authenticated Command Injection","id":"CVE-2023-2574","kev_date_added":null,"published":"2023-05-08"},{"cvss_score":8.8,"headline":"Authenticated Buffer Overflow","id":"CVE-2023-2575","kev_date_added":null,"published":"2023-05-08"}],"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":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Advantech"]},"summary":"Authenticated users can inject malicious scripts via the ping tool in Advantech EKI-152x devices, potentially compromising other users.","url":"https://insights.sbomify.com/CVE-2023-4203/"}
