Internet Security Systems Security Brief
August 11, 2003
"MS Blast" MSRPC DCOM Worm Propagation
ISS X-Force has captured active samples of an automated Internet worm that
propagates via the MS RPC DCOM vulnerability documented in ISS X-Force
Alert titled "Flaw in Microsoft Windows RPC Implementation"
(http://xforce.iss.net/xforce/alerts/id/147). This worm is currently
propagating aggressively across the Internet.
Any vulnerable desktop or server connected to the Internet may be
vulnerable to attack. All Windows 2000, Windows XP and Windows NT 4.0
computers that have not been patched are vulnerable to attack from the
automated worm, or manual attack. X-Force believes that hundreds of
thousands of computers may still be vulnerable. Unsuccessful propagation
attempts may crash vulnerable computers, or render them unstable.
Successful worm outbreaks have been known to cause significant localized
network latency, and widespread denial of service.
