# Telnet server of Schenider Electric ETY Series Controllers have a security problem. We noticed that while we are connected to the PLC through telnet, if we call telnet instance inside VxWorks again it can cause the device to crash. The telnet instance name is tTelnetd which you can see in the following line.
