Multiple Vulnerabilities in Microsoft Internet Explorer

Original issue date: February 02, 2004
Last revised: --
Source: US-CERT

Systems Affected

Microsoft Windows systems running

* Internet Explorer 5.01
* Internet Explorer 5.50
* Internet Explorer 6

Previous, unsupported, versions of Internet Explorer may also be
affected.

Overview

Microsoft Internet Explorer (IE) contains multiple vulnerabilities,
the most serious of which could allow a remote attacker to execute
arbitrary code with the privileges of the user running IE.

Description

Microsoft Security Bulletin MS04-004 describes three vulnerabilities
in Internet Explorer. These vulnerabilities are listed below. More
detailed information is available in the individual vulnerability
notes. Note that in addition to IE, any applications that use the IE
HTML rendering engine to interpret HTML documents may present
additional attack vectors for these vulnerabilities.

VU#784102 - Microsoft Internet Explorer Travel Log Cross Domain
Vulnerability

A cross-domain scripting vulnerability exists in the Travel Log
functionality of Internet Explorer. This vulnerability could allow a
remote attacker to execute arbitrary script in a different domain,
including the Local Machine Zone.
(Other resources: CAN-2003-01026)

VU#413886 - Microsoft Internet Explorer Drag-and-Drop Operation
Vulnerability

Internet Explorer allows remote attackers to direct drag and drop
behaviors and other mouse click actions by using method caching
(SaveRef) to access the window.moveBy method.
(Other resources: CAN-2003-01027)

VU#652278 - Microsoft Internet Explorer does not properly display URLs

Microsoft Internet Explorer does not properly display the location of
HTML documents. An attacker could exploit this behavior to mislead
users into revealing sensitive information.
(Other resources: CAN-2003-01025)

Impact

These vulnerabilities have different impacts, ranging from disguising
the true location of a URL to executing arbitrary commands or code.
Please see the individual vulnerability notes for specific
information. The most serious of these vulnerabilities (VU#784102)
could allow a remote attacker to execute arbitrary code with the
privileges of the user running IE. The attacker could exploit this
vulnerability by convincing the user to access a specially crafted
HTML document, such as a web page or HTML email message. No user
intervention is required beyond viewing the attacker's HTML document
with IE.

Heh, and familiar too...I remember back when we got...I guess it was the old comp that was later doomed to be fried by me (another story). It came preinstalled with IE4. I remember at one point trying to get IE out because it wouldn't coexist with Netscape for some reason (integration = NOT YOUR FRIEND! LOL) Did it go well? Only if I wanted to spend the rest of my week putting back the pieces of the messed up OS...XP

I typically try to avoid bashing stuff, but after all the problems I have had to fix due to our friendly friend Microsoft (thanks Dad for being an avid M$ supporter... ), I can say from experience that IE stinks.
