Multiple Vulnerabilities in Microsoft Internet Explorer
Original issue date: February 02, 2004
Last revised: --
Microsoft Windows systems running
* Internet Explorer 5.01
* Internet Explorer 5.50
* Internet Explorer 6
Previous, unsupported, versions of Internet Explorer may also be
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.
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
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
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)
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
