CVE-2022-37053Network attack vector

Unauthenticated command execution via gena.php request handling

Published Aug 28, 2022 · Updated Jul 9, 2026

Command injection in TRENDnet TEW733GR 1.03B01 allows remote attackers to execute arbitrary commands via the gena.php endpoint. Public records identify /htdocs/upnpinc/gena.php but do not disclose which request value reaches a command interpreter or how the command is composed. Network access to the router is sufficient; no authentication or user interaction is required, and successful exploitation gives command execution on the device.
