Georgi Guninski security advisory #6, 2000

Outlook Express 5 vulnerability - Active Scripting may read email messages

The opinions expressed in this advisory and program are my own and not of any company.
The usual standard disclaimer applies, especially the fact that Georgi Guninski is not liable for any damages caused by direct or  indirect use of the information or functionality provided by this program. Georgi Guninski, bears NO responsibility for content or misuse of this program or any derivatives thereof.

Outlook Express 5.01 and Internet Explorer 5.01 under Windows 95 (suppose other versions are also vulnerable) allow reading subsequently opened email messages after a hostile message is opened.

The problem is assigning the document object of the email message to a variable in a newly opened window.
Thru this variable access is possible to open email messages.

The code that must be included in HTML message is :
<SCRIPT>"about:<A HREF='javascript:alert(x.body.innerText)' >Click here to see the active message</A>");

Workaround: Disable Active Scripting
