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.
