The vulnerability is caused by insufficient length validation of the `account_name` parameter when processing account management requests. An attacker authenticated as a read-only user to the web\u00A0management interface could supply a specially crafted account name that exceeds the size of the internal stack buffer, resulting in corruption of program execution flow. Successful exploitation could allow an attacker to read sensitive information from device memory, including credentials, modify arbitrary memory contents, and disrupt device availability.","state":0,"publishedAt":"2026-10-02T10:18:29.907+00:00","modifiedAt":"2026-10-02T10:49:43.686+00:00","affected":[{"ecosystem":"Vendor product","name":"MGate MB3170 Series","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Moxa\",\n                    \"product\": \"MGate MB3170 Series\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0\",\n                            \"lessThanOrEqual\": \"4.7\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"},{"ecosystem":"Vendor product","name":"MGate MB3270 Series","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Moxa\",\n                    \"product\": \"MGate MB3270 Series\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"1.0\",\n                            \"lessThanOrEqual\": \"4.7\",\n                            \"versionType\": \"custom\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","score":9.4,"severity":"CRITICAL"}],"references":["https://www.moxa.com/en/support/product-support/security-advisory/mpsa-269540-cve-2026-86325,-cve-2026-86326-two-vulnerabilities-in-protocol-gateways"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-86325","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-86325","identifiers":["CVE-2026-86325"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
