RealPresence Resource Manager - Netlogon Impact

Vulnerability Summary

An elevation of privilege vulnerability exists in Netlogon when an attacker establishes a vulnerable Netlogon secure channel connection to a Microsoft Active Directory domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network. As part of their response to this, Microsoft has disabled specific protocols which may be in use for some RPRM customers. For these customers an alternate configuration is needed to restore functionality.
