Title: GrandStream GXP-2000 VoIP Desktop Phone multiple undocumented UDP ports and DoS Version: 1.1.0.5 Issues: 1.The phone has multiple undocumented open UDP ports, including 5062, 5064, 5066, 9876, 26789 2.Sending large amount of ascii data via NetCat to any open UDP port, including UDP/5060, results in the phone either rebooting or placed in a frozen state, possibly appearing normal (display maintains text, etc.), except the phone will not be functional.
