Description
Cognex In-Sight Explorer and In-Sight Camera Firmware expose a telnet-based service on port 23 in order to allow
management operations on the device such as firmware upgrades and device
reboot requiring an authentication. A wrong management of login
failures of the service allows a denial-of-service attack, leaving the telnet service
into an unreachable state.
