An attacker can exploit it over the internet without logging in, with no action from the victim."},"fix_prompt":"Check this codebase for CVE-2021-27442 and fix it if it is affected.\n\nWhat it is: CVE-2021-27442 is a critical cross-site scripting vulnerability in Weintek cMT-CTRL01, published on 16 May 2022. An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27442 in the wild and no public exploit code.\n\nAffected product: Weintek cMT-CTRL01. 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-2021-27442/ (Markdown: https://insights.sbomify.com/CVE-2021-27442/index.md)","id":"CVE-2021-27442","markdown":"https://insights.sbomify.com/CVE-2021-27442/index.md","name":"CVE-2021-27442","record":{"aliases":["GHSA-39vj-8gx7-5cj5"],"analysis":{"component_type":"iot_embedded","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Weintek HMI","requires_auth":"none","summary":"An unauthenticated remote attacker can inject malicious JavaScript into Weintek cMT HMI devices, potentially compromising user sessions or device integrity.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cmt-ctrl01_firmware","vendor":"weintek"},{"product":"cmt-fhd_firmware","vendor":"weintek"},{"product":"cmt-g01_firmware","vendor":"weintek"},{"product":"cmt-g02_firmware","vendor":"weintek"},{"product":"cmt-g03_firmware","vendor":"weintek"},{"product":"cmt-g04_firmware","vendor":"weintek"},{"product":"cmt-hdm_firmware","vendor":"weintek"},{"product":"cmt-svr-100_firmware","vendor":"weintek"},{"product":"cmt-svr-102_firmware","vendor":"weintek"},{"product":"cmt-svr-200_firmware","vendor":"weintek"},{"product":"cmt-svr-202_firmware","vendor":"weintek"},{"product":"cmt3071_firmware","vendor":"weintek"},{"product":"cmt3072_firmware","vendor":"weintek"},{"product":"cmt3090_firmware","vendor":"weintek"},{"product":"cmt3103_firmware","vendor":"weintek"},{"product":"cmt3151_firmware","vendor":"weintek"}],"cvss":{"score":9.4,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Weintek cMT product line is vulnerable to a cross-site scripting vulnerability, which could allow an unauthenticated remote attacker to inject malicious JavaScript code.","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":"Weintek EasyWeb cMT Cross-site Scripting","id":"CVE-2021-27442","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Weintek EasyWeb cMT Improper Access Control","id":"CVE-2021-27444"},"packages":[],"prev":{"headline":"Hardcoded credentials in Reason DR60","id":"CVE-2021-27440"},"products":["cMT-CTRL01","cMT-FHD","cMT-G01/G02","cMT-G03/G04","cMT-HDM","cMT-SVR-1xx/2xx","cMT3071/cMT3072/cMT3090/cMT3103/cMT3151"],"published":"2022-05-16","related":[{"cvss_score":10,"headline":"Weintek EasyWeb cMT Code Injection","id":"CVE-2021-27446","kev_date_added":null,"published":"2022-05-16"},{"cvss_score":9.8,"headline":"Weintek EasyWeb cMT Improper Access Control","id":"CVE-2021-27444","kev_date_added":null,"published":"2022-05-16"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-04-16","vendors":["Weintek"]},"summary":"An unauthenticated remote attacker can inject malicious JavaScript into Weintek cMT HMI devices, potentially compromising user sessions or device integrity.","url":"https://insights.sbomify.com/CVE-2021-27442/"}
