CVE-2026-2188Public exploitNetwork attack vector

Authenticated command execution via unsanitized policyNames

Published Feb 8, 2026 · Updated Feb 8, 2026

OS command injection in UTT 进取 521G 3.1.1-190816 allows remote authenticated users to execute arbitrary commands through policyNames. The sub_446B18 function handling /goform/formPdbUpConfig incorporates the request-body value into an operating system command without neutralizing command metacharacters. Administrative authentication is required; successful exploitation enables data access, configuration changes, or service interruption on the gateway.
