Terracotta Personal Edition Multiple vulnerabilities

Its been awhile since I've posted something, so lets get to the goods.

Terracotta is a an open source CMS from http://sourceforge.net/projects/terracotta/

First up, we have Full path disclosure vulnerabilities in the GET'd variable 'File'. Specify something other than whats
in the list and we get full paths and other useful information.

Next we have some nice LFI.

To LFI this code, we try the following:

www.example.com/index.php?CurrentDirectory=FOLDER_420c142a1bebd1.90885049/../../../../../../../../../etc/&StartAt=12

The GET'd variable Current directory fails to check for other invalid input allowing us to specifiy folders outside the
normal program's environment. though we can only specify folders, it will display them for us as if it were part of its
normal viewing procedures.

To add insult to injury, there is another parameter present for download processing that we can manipulate to specify
which file we want.
www.example.com/index.php?CurrentDirectory=FOLDER_420c142a1bebd1.90885049/../../whatever/&StartAt=12&File=whateverwewant.txt

This used in conjunction with our full path disclosures allow for some directory and file probing as well as a peek at
server side code.

No patch yet. Happy hunting!
