Details:  
========  
Multiple persistent input validation vulnerabilities are detected in the Croogo v1.3.4 Content Management System.   
The bugs allow remote attackers to implement/inject malicious script code on the application side (persistent). Successful exploitation   
of the vulnerability can lead to session hijacking (manager/admin) or stable (persistent) context manipulation. Exploitation requires   
low user inter action. Attackers can inject malicious strings as username to execute them when a admin is processing to view, review   
or list username or names. The bug is located on application side & the execution is persistent out of the web application context.  
  
Vulnerable Module(s):  
[+] User Listing - Username & Name  
[+] Role Listing - Name & Alias

Proof of Concept:  
=================  
The vulnerability can be exploited by remote attackers with low required user inter action. For demonstration or reproduce ...

Risk:  
=====  
The security risk of the persistent input validation vulnerabilities are estimated as medium(+).
