Description

There is a remote code execution vulnerability in Server Service that could allow an attacker who successfully exploited this vulnerability to take complete control of the affected system.



Impact

An attacker who successfully exploited this vulnerability could take complete control of the affected system.



Technical details (analysis)

The Server service provides RPC support, file print support and named pipe sharing over the network. The Server service allows the sharing of your local resources (such as disks and printers) so that other users on the network can access them. It also allows named pipe communication between applications running on other computers and your computer, which is used for RPC. An attacker could try to exploit the vulnerability by creating a specially crafted message and sending the message to an affected system. The message could then cause the affected system to execute code.



Affected software

Microsoft Windows 2000 Service Pack 4
Microsoft Windows XP Service Pack 1 and Microsoft Windows XP Service Pack 2
Microsoft Windows XP Professional x64 Edition
Microsoft Windows Server 2003 and Microsoft Windows Server 2003 Service Pack 1
Microsoft Windows Server 2003 for Itanium-based Systems and Microsoft Windows Server 2003 with SP1 for Itanium-based Systems
