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-2021-32943 in the wild and no public exploit code.\n\nAffected product: WebAccess/SCADA. 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-2021-32943/ (Markdown: https://insights.sbomify.com/CVE-2021-32943/index.md)","id":"CVE-2021-32943","markdown":"https://insights.sbomify.com/CVE-2021-32943/index.md","name":"CVE-2021-32943","record":{"aliases":["GHSA-pg6r-cmxx-v6vf"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SCADA software","requires_auth":"none","summary":"A stack-based buffer overflow in WebAccess/SCADA allows remote attackers to execute arbitrary code, requiring an upgrade to secure the system.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"webaccess\\/scada","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":"The affected product is vulnerable to a stack-based buffer overflow, which may allow an attacker to remotely execute arbitrary code on the WebAccess/SCADA (WebAccess/SCADA versions prior to 8.4.5, WebAccess/SCADA versions prior to 9.0.1).","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/SCADA","id":"CVE-2021-32943","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"Use after free in Drawings SDK","id":"CVE-2021-32944"},"packages":[],"prev":{"headline":"Information disclosure in InTouch","id":"CVE-2021-32942"},"products":["WebAccess/SCADA"],"published":"2021-08-10","related":[{"cvss_score":9.8,"headline":"CVE-2023-1437","id":"CVE-2023-1437","kev_date_added":null,"published":"2023-08-02"},{"cvss_score":9.8,"headline":"Auth bypass in n/a","id":"CVE-2019-6519","kev_date_added":null,"published":"2019-02-05"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2019-6523","kev_date_added":null,"published":"2019-02-05"},{"cvss_score":8.8,"headline":"Privilege escalation in Advantech WebAccess/SCADA","id":"CVE-2021-22669","kev_date_added":null,"published":"2021-04-26"},{"cvss_score":8.8,"headline":"Privilege escalation in Advantech","id":"CVE-2020-13554","kev_date_added":null,"published":"2021-03-03"},{"cvss_score":8.8,"headline":"Path traversal in Advantech WebAccess/SCADA","id":"CVE-2020-25161","kev_date_added":null,"published":"2021-02-23"}],"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":"2024-08-03","vendors":["n/a"]},"summary":"A stack-based buffer overflow in WebAccess/SCADA allows remote attackers to execute arbitrary code, requiring an upgrade to secure the system.","url":"https://insights.sbomify.com/CVE-2021-32943/"}
