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-2021-38432 in the wild and no public exploit code.\n\nAffected product: FATEK Automation Communication Server. 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-2021-38432/ (Markdown: https://insights.sbomify.com/CVE-2021-38432/index.md)","id":"CVE-2021-38432","markdown":"https://insights.sbomify.com/CVE-2021-38432/index.md","name":"CVE-2021-38432","record":{"aliases":["GHSA-2qjg-mr5r-c2hw"],"analysis":{"component_type":"ics_ot","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial Automation Server","requires_auth":"none","summary":"A stack-based buffer overflow in FATEK Automation Communication Server allows remote attackers to execute arbitrary code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"communication_server_firmware","vendor":"fatek"}],"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-121","name":"Stack-based Buffer Overflow"}],"description":"FATEK Automation Communication Server Versions 1.13 and prior lacks proper validation of user-supplied data, which could result in a stack-based buffer overflow condition and allow an attacker to remotely execute 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":"FATEK Automation Communication Server","id":"CVE-2021-38432","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":"RTI Connext DDS Professional and Connext DDS Secure Stack-based Buffer Overflow","id":"CVE-2021-38433"},"packages":[],"prev":{"headline":"Advantech WebAccess SCADA","id":"CVE-2021-38431"},"products":["Communication Server"],"published":"2021-10-15","related":[],"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":"2024-09-16","vendors":["FATEK Automation"]},"summary":"A stack-based buffer overflow in FATEK Automation Communication Server allows remote attackers to execute arbitrary code.","url":"https://insights.sbomify.com/CVE-2021-38432/"}
