Who is Vulnerable?
Vulnerability Description	Intellicom NetBiter webSCADA is an embedded SCADA (Supervisory Control And Data Acquisition) solution for various hardware devices, providing remote management through web browsers. NetBiter webSCADA ships with a configuration utility NetBiter Config used to enumerate and configure compatible devices on the LAN. A buffer overflow vulnerability exists in Intellicom NetBiter Config utility that can allow for arbitrary code execution. The vulnerability is due to a boundary error in 'NetbiterConfig.exe' while parsing a certain parameter. Remote unauthenticated attackers can exploit this vulnerability by sending a crafted UDP packet to port 3250 on the target host. Once the packet is received a NetBiter Config console user must be enticed to open the received message. Successful exploitation would allow for executing arbitrary code on the target with the privileges of the currently logged on user. In a case where code execution is unsuccessful, the service will terminate abnormally.
