Microsoft Windows IPsec Policy Information Disclosure Vulnerability( 13 August 2008 )

An information disclosure vulnerability exists in the manner in which IPsec policies are imported to Windows Server 2008 domains from Windows Server 2003 domains. This vulnerability could cause systems to ignore IPsec policies and transmit network traffic in clear text. This, in turn, would potentially disclose information intended to be encrypted on the network. An attacker intercepting the traffic on the network would be able to view and possibly modify the contents of the traffic. Note that this vulnerability would not allow an attacker to execute code or to elevate their user rights directly. It could be used to collect useful information to try to further compromise the affected system.
