Description:
Keene Digital Media Server is an easy and affordable way to
share all things digital with friends, family, and customers
over your broadband connection. DMS turns your computer into
a highly secure Web server that automatically converts your
files and folders into Web pages, thumbnails, and media shows
with no Web programming required. Integrated user and file
access security management provide the ultimate control over
your content.
Directory Traversal Vulnerability:
Not too long ago i saw there was a directory traversal vuln
found in Keene Digital Media Server. it was fixed by the
developers, but
http://localhost/%2E%2E%5Csystem.log
It seems that only ../ and %2E%2E/ were filtered out. If you
hex encode the backslash or use a forward slash you can then
traverse out of the web directory. For example I am able to
grab the server log file with the above request.
Solution:
I contacted the developers but never received a response.
