(https://support.microsoft.com/kb/318203/EN-US/ )MS02-008: XMLHTTP Control in MSXML 3.0 Can Allow Access to Local Files
An information-disclosure vulnerability exists that could allow an attacker to read files on the local file system of a user who visits a specially malformed web site.
The attacker would not be able to add, change, or delete files. In addition, the attacker would not be able to use e-mail to carry out this attack; the vulnerability can only be exploited by way of a Web site. Customers who exercise caution when browsing and avoid visiting unknown or untrustworthy sites are at less risk from this vulnerability.
The vulnerability exists because the XMLHTTP control in the Microsoft XML Core Services does not respect the Internet Explorer Security Zone restrictions. This enables a Web page to specify a file on a user's local system as an XML data source as a means of reading the file.
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that this article describes. Apply it only to systems that you determine are at risk of attack. Evaluate the computer's physical accessibility, network and Internet connectivity, and other factors to determine the degree of risk to the computer. See the associated Microsoft Security Bulletin
(http://www.microsoft.com/technet/security/bulletin/MS02-008.mspx)to help determine the degree of risk. This hotfix may receive additional testing. If the computer is sufficiently at risk, we recommend that you apply this hotfix now.
