TOTOLINK X2000R router: batchupg flaw lets an authenticated user run commands

TOTOLINK X2000R firmware B20250421.1327 has an OS command injection in batchupg. A logged-in admin can upload a file with a crafted filename (/boafrm/formUploadFile), trigger /boafrm/formBuploadSetting, and the filename reaches system() unsanitised, giving command execution as the router. Found by Cisco Talos. The vendor acknowledged the report in June 2026 but no fixed firmware is published.
