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.
mshtml.dll in Microsoft Internet Explorer 6.0.2800 allows remote attackers to cause a denial of service (crash) via a table containing a form that crosses multiple td elements, and whose "float: left" class is defined in a link to a CSS stylesheet after the end of the table, which may trigger a null dereference.
Microsoft Internet Explorer allows remote attackers to cause a denial of service (resource consumption) via a Javascript src attribute that recursively loads the current web page.
The Javascript "Same Origin Policy" (SOP), as implemented in (1) Netscape, (2) Mozilla, and (3) Internet Explorer, allows a remote web server to access HTTP and SOAP/XML content from restricted sites by mapping the malicious server's parent DNS domain name to the restricted site, loading a page from the restricted site into one frame, and passing the information to the attacker-controlled frame, which is allowed because the document.domain of the two frames matches on the parent domain.
Stack consumption vulnerability in Internet Explorer The JavaScript settimeout function in Internet Explorer allows remote attackers to cause a denial of service (crash) via the JavaScript settimeout function. NOTE: the vendor could not reproduce the problem.
Internet Explorer, with a security setting below Medium, allows remote attackers to execute arbitrary commands via a malicious web page that uses the FileSystemObject ActiveX object.
A configuration in a web browser such as Internet Explorer or Netscape Navigator allows execution of active content such as ActiveX, Java, Javascript, etc.
