Attack developed within two days of disclosure.
The Workstation Service flaw announced and patched on Tuesday, one of the most critical vulnerabilities covered by Microsoft's monthly updates, has been targeted by an exploit within two days.
The security hole, covered by Microsoft Security Bulletin MS06-070, particularly affects Windows 2000 users, who could be at risk of complete system intrusion without user interaction or authentication. XP users are believed to be safer, as administrator privileges are more closely guarded.
The speed with which the exploit has been developed may catch out users who are slow to update, and the hole has been described as an ideal vector for a fast-spreading worm. Anyone still running Windows 2000 is advised to apply the patch as soon as possible.
Microsoft's bulletin is here, and the Windows 2000 version of the patch is here. Symantec has released generic detection for such exploits, with some details here.
