Subject: XSS in Celoxis project management software
==Background==
>>From Celoxis.com:
> Celoxis is a comprehensive web based project management
> tool to improve collaboration and streamline management
> of projects, time sheets, expenses and even business
> processes specific to your organization
==Problem==
The Celoxis project management software contains several pages that
accept parameters in their URLs and display the contents of those
parameters as page content. Many of these parameters may contain
HTML tags, including the <script> tag, and in most cases their
content is not sanitized in any way. These parameters are used
internally by the software to display messages to the end user.
Most of these pages are only accessible with a paid or trial
subscription.
==Proof of Concept==
The following POC may be accessed without a subscription:
http://asp1.celoxis.com/psa/user.do?bxn=umyhome&ni.smessage=XSS+goes
+here+%3cscript%3ealert('XSS')%3c/script%3e
==Potential Impact==
This vulnerability can be used to manipulate arbitrary objects
within the application without user authorization. Objects include
projects, tasks, users, etc. It appears to be possible to exploit
this vulnerability to cause users to delete their own projects.
