CVE-2008-2246: Microsoft Windows-Nt

High severity, CVSS 7.8. EPSS: 32.1% chance of exploitation in the next 30 days.

Microsoft Windows Vista through SP1 and Server 2008 do not properly import the default IPsec policy from a Windows Server 2003 domain to a Windows Server 2008 domain, which prevents IPsec rules from being enforced and allows remote attackers to bypass intended access restrictions.

Affected products

• Microsoft Windows-Nt: version 2008 only
• Microsoft Windows Vista: any version; affected versions not specified
