The specific flaw exists within the Hewlett-Packard Client Automation agent. An attacker can send a large buffer of data to the agent which will cause a stack buffer overflow. An attacker can leverage this vulnerability to execute code under the context of the SYSTEM.
05/28/2015 - ZDI sent the report to HP SSRT (believing the product was licensed to or by HP).
Given the nature of the vulnerability, the only salient mitigation strategy is to restrict interaction with the service to trusted machines. Only the clients and servers that have a legitimate procedural relationship with the service should be permitted to communicate with it. This could be accomplished in a number of ways, most notably with firewall rules/whitelisting. These features are available in the native Windows Firewall, as described in http://technet.microsoft.com/en-us/library/cc725770%28WS.10%29.aspx and numerous other Microsoft Knowledge Base articles.
