An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-4483 in the wild and no public exploit code.\n\nAffected product: Moxa MxGeneralIo. 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-2026-4483/ (Markdown: https://insights.sbomify.com/CVE-2026-4483/index.md)","id":"CVE-2026-4483","markdown":"https://insights.sbomify.com/CVE-2026-4483/index.md","name":"CVE-2026-4483","record":{"aliases":["GHSA-9fq9-vh4p-342c"],"analysis":{"component_type":"operating_system","fix_type":"no_fix_stated","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial computer utility","requires_auth":"high_privilege","summary":"A local attacker with high privileges can exploit exposed IOCTLs in MxGeneralIo to escalate privileges or cause a system crash.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Moxa","cpe":[],"cvss":{"score":7,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:L/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-782","name":"Exposed IOCTL with Insufficient Access Control"}],"description":"An exposed IOCTL with an  insufficient access control vulnerability has been identified in the utility, MxGeneralIo, for Moxa’s industrial x86 computers. The affected utility, MxGeneralIo, exposes IOCTL methods that permit direct read and write access to MSR and system memory. A local attacker with high privileges could abuse these interfaces to perform unauthorized operations. Successful exploitation may result in privilege escalation on Windows 7 systems or cause a system crash (BSoD) on Windows 10 and 11 systems, leading to a denial-of-service condition. The vulnerability could slightly affect the confidentiality and integrity of the device, but availability might be heavily impacted. No impact to the subsequent system has been identified.","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":"Privilege escalation in MxGeneralIo","id":"CVE-2026-4483","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Masteriyo LMS \u003c= 2.1.6 - Missing Authorization to Authenticated (Student+) Privilege Escalation to Administrator","id":"CVE-2026-4484"},"packages":[],"prev":{"headline":"Insight Agent Private Key Information Disclosure via Inherited File Permissions","id":"CVE-2026-4482"},"products":["MxGeneralIo"],"published":"2026-04-08","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-04-08","vendors":["Moxa"]},"summary":"A local attacker with high privileges can exploit exposed IOCTLs in MxGeneralIo to escalate privileges or cause a system crash.","url":"https://insights.sbomify.com/CVE-2026-4483/"}
