Signature Detail

HTTP: Internet Explorer Drag-and-Drop Evasion

This signature detects attempts to exploit a known vulnerability against Microsoft Internet Explorer drag-and-drop. Attackers can send a maliciously crafted request or host a malicious Web page to exploit this issue. A successful attack can allow attackers to execute arbitrary code. This vulnerability is detailed in Microsoft Security Bulletin MS04-038.

Extended Description

The Microsoft cumulative Internet Explorer patch (MS04-038) attempted to limit what files may be dragged and dropped onto the local computer from the Internet Zone to prevent executable objects from being placed on the file system in this manner. However, a number of file types are still permitted for drag and drop operations. It has demonstrated that it is possible to embed hostile HTML and script code in one of these file types, remove the file extension and then allow the operating system to dynamically determine the file type based on its contents. If this issue were combined with other vulnerabilities, such as that described in BID 11467, it may result in execution of arbitrary code on the client computer. Both Internet Explorer and Microsoft Windows itself is affected by this vulnerability.
