OIS Advisory (CA20030812): Potential For Significant Impact On Internet Operations Due To Vulnerability In Microsoft Operating Systems (2nd UPDATE: Worm Spreading on the Internet)
The UGA Office of Information Security has received the following updated advisory from the Department of Homeland Security concerning the propagation of the W32/Blaster worm that exploits the recent Microsoft RPC vulnerability.
SYSTEMS AFFECTED:
Computers using the following operating systems:
Microsoft Windows NT 4.0
Microsoft Windows NT 4.0 Terminal Services Edition
Microsoft Windows 2000
Microsoft Windows XP
Microsoft Windows Server 2003
OVERVIEW:
DHS expects that exploits are being developed for malicious use. Two additional factors are causing heightened interest in this situation: the affected operating systems are in wide spread use, and exploitation of the vulnerability could permit the execution of arbitrary code. DHS and Microsoft are concerned that a properly written exploit could rapidly spread on the Internet as a worm or virus in a fashion similar to Code Red or Slammer. (2nd UPDATE: MALICIOUS CODE DUBBED "MSBLAST", "LOVESAN", OR "BLASTER" BEGAN CIRCULATING ON THE INTERNET ON AUGUST 11TH. THIS WORM TAKES ADVANTAGE OF THE VULNERABILITY DISCUSSED IN THIS ADVISORY, AND CONTAINS CODE THAT WILL TARGET MICROSOFT'S UPDATE SERVERS ON AUGUST 16TH. THIS ADDITIONAL ATTACK COULD CAUSE SIGNIFICANT INTERNET-WIDE DISRUPTIONS. IT IS POSSIBLE THAT OTHER WORMS BASED ON THIS VULNERABILITY WILL BE RELEASED OVER THE NEXT FEW DAYS AS "COPY CAT" ATTACKS.)
