Apple Safari local file theft vulnerability

Apple Safari local file theft vulnerability



Hi,

Safari prior to version 4 may permit an evil web page to steal files
from the local system.

This is accomplished by mounting an XXE attack against the parsing of
the XSL XML. This is best explained with a sample evil XSL file which
includes a DTD that attempts the XXE attack:

 ] >
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 

  
  
Below you should see the content of a local file, stolen by this evil web page.

&ent; To mount the attack, the attacker would serve a web page which has XML MIME type and requests to be styled by the evil stylesheet: irrelevant Full technical details: http://scary.beasts.org/security/CESA-2009-006.html Blog post: http://scarybeastsecurity.blogspot.com/2009/06/apples-safari-4-fixes-local-file-theft.html (includes 1-click demos) Cheers Chris
