Microsoft Internet Explorer 6 allows remote attackers to spoof the address bar to facilitate phishing attacks via Javascript that uses an invalid URI, modifies the Location field, then uses history.back to navigate to the previous domain, aka NullyFake.

Microsoft Windows Internet Explorer 5.5 and 6.0 allows remote attackers to execute arbitrary code via an embedded script that uses Shell Helper objects and a shortcut (link) to execute the target script.

Microsoft Internet Explorer 5.0 through 6.0 allows remote attackers to bypass cross-frame scripting restrictions and capture keyboard events from other domains via an HTML document with Javascript that is outside a frameset that includes the target domain, then forcing the frameset to maintain focus. NOTE: the discloser claimed that the vendor does not categorize this as a vulnerability, but it can be used in a spoofing scenario; the discloser provides alternate scenarios. Spoofing scenarios are currently included in CVE.

Microsoft Internet Explorer 6.0 SP1 allows remote attackers to cause a denial of service (browser crash) via a link with "::{" (colon colon left brace), which triggers a null dereference when the user attempts to save the link using "Save As" and Internet Explorer prepares an error message with an attacker-controlled format string.

Internet Explorer 5.01 through 6 allows remote attackers to spoof arbitrary web sites by injecting content from one window into another window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability. NOTE: later research shows that Internet Explorer 7 on Windows XP SP2 is also vulnerable.

Internet Explorer 6.x on Windows XP SP2 allows remote attackers to execute arbitrary code, as demonstrated using a document with a draggable file type such as .xml, .doc, .py, .cdf, .css, .pdf, or .ppt, and using ADODB.Connection and ADODB.recordset to write to a .hta file that is interpreted in the Local Zone by HTML Help.

Microsoft Internet Explorer 6.0 SP2 allows remote attackers to spoof a legitimate URL in the status bar and conduct a phishing attack via a web page that contains a BASE element that points to the legitimate site, followed by an anchor (a) element with an empty "href" attribute, and a FORM whose action points to a malicious URL, and an INPUT submit element that is modified to look like a legitimate URL.

CRLF injection vulnerability in Microsoft Internet Explorer 6.0.2800.1106 and earlier allows remote attackers to execute arbitrary FTP commands via an ftp:// URL that contains a URL-encoded newline ("%0a") before the FTP command, which causes the commands to be inserted into the resulting FTP session, as demonstrated using a PORT command.

Heap-based buffer overflow in Internet Explorer 6 allows remote attackers to execute arbitrary code via long (1) SRC or (2) NAME attributes in IFRAME, FRAME, and EMBED elements, as originally discovered using the mangleme utility, aka "the IFRAME vulnerability" or the "HTML Elements Vulnerability."

Internet Explorer on Windows XP does not properly modify the "Drag and Drop or copy and paste files" setting when the user sets it to "Disable" or "Prompt," which may enable security-sensitive operations that are inconsistent with the user's intended configuration.
