Windows Server Service RPC Overflow Remote Code Execution
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An unauthenticated attacker, remotely over the network, with no user interaction, can fully compromise the system — steal data, tamper with it and take it offline.
The Server service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, and 7 Pre-Beta allows remote attackers to execute arbitrary code via a crafted RPC request that triggers the overflow during path canonicalization, as exploited in the wild by Gimmiv.A in October 2008, aka "Server Service Vulnerability."

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
Immediately restrict inbound network access to TCP ports 139 and 445 (SMB) at the network perimeter firewall and on host-based firewalls, allowing access only from trusted internal networks. Implement network intrusion detection systems (NIDS) to monitor for unusual RPC or SMB traffic patterns indicative of exploitation attempts. Prioritize applying these network controls on all vulnerable Windows systems, especially domain controllers and critical servers.
The permanent resolution is to apply the Microsoft security update associated with MS08-067 without delay. All affected Windows 2000 SP4, XP SP2/SP3, Server 2003 SP1/SP2, Vista Gold/SP1, Server 2008, and Windows 7 Pre-Beta systems must be patched. Ensure systems are updated to the latest available service packs and security patches, or consider upgrading to currently supported operating system versions.
A remote unauthenticated attacker can execute arbitrary code with SYSTEM privileges on affected systems by sending a specially crafted RPC request. This critical vulnerability allows complete control over the compromised host, leading to data exfiltration, service disruption, and potential lateral movement across the network. The business consequences include significant operational downtime, data loss, and severe reputational damage.
