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-2020-12019 in the wild and no public exploit code.\n\nAffected product: Advantech Webaccess. 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-2020-12019/ (Markdown: https://insights.sbomify.com/CVE-2020-12019/index.md)","id":"CVE-2020-12019","markdown":"https://insights.sbomify.com/CVE-2020-12019/index.md","name":"CVE-2020-12019","record":{"aliases":["GHSA-fx8h-mcx2-mhjf"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WebAccess Node","requires_auth":"none","summary":"A stack-based buffer overflow in WebAccess Node allows remote attackers to execute arbitrary code, posing a critical risk to industrial control systems.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess","vendor":"advantech"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","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":"WebAccess Node Version 8.4.4 and prior is vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute arbitrary 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":"Memory corruption in WebAccess Node","id":"CVE-2020-12019","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"advantech:webaccess","products":["advantech:webaccess"],"type":"memory_corruption","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Baxter ExactaMix EM 2400 \u0026 EM 1200","id":"CVE-2020-12020"},"packages":[],"prev":{"headline":"Information disclosure in Advantech WebAccess Node","id":"CVE-2020-12018"},"products":["WebAccess Node"],"published":"2020-06-15","related":[{"cvss_score":10,"headline":"Multiple stack-based buffer overflows in unspecified DLL files in Advantech WebAccess before 8.0.1 allow remote attackers to execute arbitra","id":"CVE-2014-9208","kev_date_added":null,"published":"2015-09-11"},{"cvss_score":9.8,"headline":"Advantech WebAccess","id":"CVE-2021-33023","kev_date_added":null,"published":"2021-10-18"},{"cvss_score":9.8,"headline":"Advantech WebAccess","id":"CVE-2021-38389","kev_date_added":null,"published":"2021-10-18"},{"cvss_score":9.8,"headline":"Memory corruption in Advantech WebAccess","id":"CVE-2021-38408","kev_date_added":null,"published":"2021-09-09"},{"cvss_score":9.8,"headline":"Memory corruption in Advantech WebAccess Node","id":"CVE-2020-10638","kev_date_added":null,"published":"2020-05-08"},{"cvss_score":9.8,"headline":"Memory corruption in Advantech WebAccess Node","id":"CVE-2020-12002","kev_date_added":null,"published":"2020-05-08"}],"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"A stack-based buffer overflow in WebAccess Node allows remote attackers to execute arbitrary code, posing a critical risk to industrial control systems.","url":"https://insights.sbomify.com/CVE-2020-12019/"}
