This is true, however LimeWire does ask at time of installation if it can search your harddrive for files to share. I did not choose this feature when I tested LimeWire, but am now curious if LimeWire copies such files to the 'shared' folders (which I doubt), or does it flag those files (or heaven help us, folders) as sharable. This may be the source of a directory traversal vuln.

By default it does not share the whole harddrive but it is a simple click of a mouse that gives the whole thing up. I was thinking more along the lines of people dumping the same file. Browse host rarely works. Hope that helps, Leon Ps: I am saying most people tend to mis configure (ie share the whole harddrive) this is NOT the default behavior. So no there is no directory traversal vuln. -----Original Message----- From: Steve Skoronski [mailto:skoronskiat_private] Sent: Monday, October 01, 2001 3:08 PM To: 'leon' Cc: 'vuln-devat_private' Subject: RE: limewire cookie (among others) disclosure vuln I fully agree that if someone was sharing their entire hard drive this would be a really bad thing in terms of ability to compromise the machine. I just installed limewire and it defaulted my shared directory to \limewire1.7\shared\ Do you have a way of bypassing this? Some sort of directory traversal? I tried searching for things like 'rundll' and came up with lots! If the shared directory is default, are people manually changing this to C:\ ?! Also, not getting much luck using the 'browse host' function, it doesn't seem to return anything. Telneting directly to the host on TCP 6347 yielded nothing either. -----Original Message----- From: leon [mailto:leonat_private] Sent: Sunday, September 30, 2001 2:00 PM To: vuln-devat_private Subject: limewire cookie (among others) disclosure vuln Hi everyone, Aleph One suggested I post this here to get a more polished version for an advisory. Here is what I have found and I am sure most of the people here can test this and develop it even further. Limewire is a gnutella file sharing client. Due to common misconfigurations by the user, people are sharing their whole harddrives. This means you can do everything from downloading someone's quicken data file (quicken is a money management program) to downloading cookies off peoples hard drives. Who cares about the cookies you say? Well I have found cookies from certain sites that contains people user name & password stored in clear text. I am sure with enough testing you could figure out a way to dump the sam file off an NT box or etc etc. Anyone who wants to run with this great I would just appreciate if you do further the research you let me know what you find. Cheers Vuln-Dev, Leon ps: sorry for screwing up the packet capture on the aol im 0-day post.
