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-2023-43492 in the wild and no public exploit code.\n\nAffected product: Weintek cMT-FHD. 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-2023-43492/ (Markdown: https://insights.sbomify.com/CVE-2023-43492/index.md)","id":"CVE-2023-43492","markdown":"https://insights.sbomify.com/CVE-2023-43492/index.md","name":"CVE-2023-43492","record":{"aliases":["GHSA-6gp7-g3rx-2cq6"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"HMI Web CGI","requires_auth":"none","summary":"An anonymous attacker can exploit a stack-based buffer overflow in the HMI web interface to hijack control flow and bypass authentication.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"cmt-fhd_firmware","vendor":"weintek"},{"product":"cmt-hdm_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":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"In Weintek's cMT3000 HMI Web CGI device, the cgi-bin codesys.cgi contains a stack-based buffer overflow, which could allow an anonymous attacker to hijack control flow and bypass login authentication.","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 cMT3000 HMI Web CGI Stack-based Buffer Overflow","id":"CVE-2023-43492","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"SQL injection in Welcart e-Commerce","id":"CVE-2023-43493"},"packages":[],"prev":{"headline":"Information disclosure in Smart Reader","id":"CVE-2023-43491"},"products":["cMT-FHD","cMT-HDM","cMT3071","cMT3072","cMT3090","cMT3103","cMT3151"],"published":"2023-10-19","related":[{"cvss_score":9.8,"headline":"Weintek cMT3000 HMI Web CGI Stack-based Buffer Overflow","id":"CVE-2023-38584","kev_date_added":null,"published":"2023-10-19"},{"cvss_score":8.8,"headline":"Weintek cMT3000 HMI Web CGI OS Command Injection","id":"CVE-2023-40145","kev_date_added":null,"published":"2023-10-19"}],"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":"2025-01-16","vendors":["Weintek"]},"summary":"An anonymous attacker can exploit a stack-based buffer overflow in the HMI web interface to hijack control flow and bypass authentication.","url":"https://insights.sbomify.com/CVE-2023-43492/"}
