Signature Detail

MS-RPC: RPC DNS Server

This signature detects attempts to exploit a known vulnerability against Microsoft DNS Server. A remote code execution vulnerability exists in the RPC interface of Microsofts DNS Server because of the way that it handles certain RPC functions. Microsoft Windows 2000 Server Service Pack 4, Windows Server 2003 Service Pack 1, and Windows Server 2003 Service Pack 2 are affected. A successful attack allows arbitrary code execution at SYSTEM level.

Extended Description

Microsoft Windows Domain Name System (DNS) Server Service is prone to a stack-based buffer-overflow vulnerability in its Remote Procedure Call (RPC) interface. A remote attacker may exploit this issue to run arbitrary code in the context of the DNS Server Service. The DNS service runs in the 'SYSTEM' context. Successfully exploiting this issue allows attackers to execute arbitrary code, facilitating the remote compromise of affected computers. Windows Server 2000 Service Pack 4, Windows Server 2003 Service Pack 1, and Windows Server 2003 Service Pack 2 are confirmed vulnerable to this issue. Microsoft Windows 2000 Professional SP4, Windows XP SP2, and Windows Vista are not affected by this vulnerability.
