RPCS/RPMS Appliances - Exposure of Sensitive System Information to an Unauthorized Control Sphere
Appliance Edition models of Poly RealPresence Capture Server and RealPresence Media Suite were delivered with a default configuration that exposed an IPMI administrative web interface with default credentials, when deployed on a network with DHCP.
Poly has implemented changes to the default configuration of RealPresence Media Suite to address these issues. Media Suite administrators can download system updates on the Poly Support Site.
The Baseboard Management Controller (BMC) on appliance edition hardware supports the Intelligent Platform Management Interface (IPMI). As shipped, the IPMI was configured to share the LAN 1 port but used a separate MAC address unique from the system.
On networks with DHCP service, this shared IPMI port was default configured to make a DHCP request and claim a unique network address. The IPMI subsystem would run a webserver that provided administrator-level access using default credentials to a variety of system configuration options.

|Poly RPCS/RPMS Appliance Edition||
Poly recommends customers upgrade to RealPresence Media Suite version 2.1 build.
For customers who cannot upgrade to RealPresence Media Suite version 2.1 or newer, this issue will be mitigated in environments without a DHCP server on the same subnet as the appliance.
In network environments where DHCP is necessary, we recommend implementing either a whitelist or a blacklist on the DHCP server to disallow the IPMI system from claiming an address. In addition, we recommend administrators follow standard best practices and always restrict network access to the management interface of the appliance.
In environments with DHCP enabled, the network address of the webserver running on the IPMI port can be detected by closely observing the startup routine of the appliance console, or by using a network scan, sniffing the network for DHCP requests, or by monitoring the logs of the DHCP server.
Any customer using an affected system who is concerned about this vulnerability within their deployment should contact Poly Technical Support – (888) 248-4143, (916) 928-7561, or visit the Poly Support Site.
