Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".
Unknown versions of Internet Explorer and Outlook allow remote attackers to spoof a legitimate URL in the status bar via A HREF tags with modified "alt" values that point to the legitimate site, combined with an image map whose href points to the malicious site, which facilitates a "phishing" attack.
The WebBrowser ActiveX control, or the Internet Explorer HTML rendering engine (MSHTML), as used in Internet Explorer 6, allows remote attackers to execute arbitrary code in the Local Security context by using the showModalDialog method and modifying the location to execute code such as Javascript, as demonstrated using (1) delayed HTTP redirect operations, and an HTTP response with a Location: header containing a "URL:" prepended to a "ms-its" protocol URI, or (2) modifying the location attribute of the window, as exploited by the Download.ject (aka Scob aka Toofer) using the ADODB.Stream object.
Internet Explorer for Mac 5.2.3, Internet Explorer 6 on Windows XP, and possibly other versions, does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.
Microsoft Internet Explorer allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Internet Explorer to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.
Microsoft Internet Explorer 5.0.1 through 6.0 allows remote attackers to determine the existence of arbitrary files via the VBScript LoadPicture method, which returns an error code if the file does not exist.
Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and execute Javascript by setting the window's "href" to the malicious Javascript, then calling execCommand("Refresh") to refresh the page, aka BodyRefreshLoadsJPU or the "ExecCommand Cross Domain" vulnerability.
Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions and read arbitrary files by (1) modifying the createTextRange method and using CreateLink, as demonstrated using LinkillerSaveRef, LinkillerJPU, and Linkiller, or (2) modifying the createRange method and using the FIND dialog to select text, as demonstrated using Findeath, aka the "Function Pointer Override Cross Domain" vulnerability.
Internet Explorer 6 SP1 and earlier allows remote attackers to bypass zone restrictions by (1) using the NavigateAndFind method to load a file: URL containing Javascript, as demonstrated by NAFfileJPU, (2) using the window.open method to load a file: URL containing Javascript, as demonstrated using WsOpenFileJPU, (3) setting the href property in the base tag for the _search window, as demonstrated using WsBASEjpu, (4) loading the search window into an Iframe, as demonstrated using WsFakeSrc, (5) caching a javascript: URL in the browser history, then accessing that URL in the same frame as the target domain, as demonstrated using WsOpenJpuInHistory, NAFjpuInHistory, BackMyParent, BackMyParent2, and RefBack, aka the "Script URLs Cross Domain" vulnerability.
