Description
Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based service on port 23 to allow management operations such as firmware upgrades and device reboots, which require authentication. A user with protected privileges can successfully invoke the SetSerialPort functionality to modify relevant device properties (such as serial interface settings), contradicting the security model proposed in the user manual.
