Validated Vulnerable:   
All previous version of SugarCRM prior to 5.5.0a and 5.2.0l   
A Stored Cross-Site Scripting (XSS) vulnerability was found within  
SugarCRM. The vulnerability is exploited through the online Documents  
section of the application. By crafting a name that includes XSS code it  
is possible to inject malicious data, redirect the user to a bogus  
replica of the real website, or other nefariousactivity.   
There are two ways that have been used to exploit this vulnerability. In  
both instances, make a document with the following Document Name:   
pwn3d<SCRIPT SRC=""></SCRIPT>  
Example #1  
Within the SugarCRM User Interface (UI) go to the Documents List. Click  
on the one just created. This will execute the script. You will see the  
script right in the document list- very obvious to most users that  
something doesn't look right. The next example is slighly more covert.  
Example #2  
Within the SugarCRM UI go to the Document List. Hover over the Document  
Name you just created, right-click, and then copy the URL location. You  
will see the URL does not have any of the scripting, it has been  
replaced with queries directly to a Record variable within the  
application. This would probably be the tact a Phisher would take.  
A patch has been made available via the vendor. It is recommended a  
routine to sanitize user input be consistently implemented throughout  
the application to mitigate other such occurrences within the
