Technical Details & Description:
================================
Multiple persistent cross site web vulnerabilities has been discovered in the priceel cms (v2015) online-service web-application.
The vulnerability allows remote attackers to inject own malicious script codes with persistent attack vector to compromise 
browser to web-application requests from the application-side.

The vulnerabilities are located in the `name` and `title` parameters of the (`edit_productcategory`, `edit_activity`, 
`edit_brand`, `edit_photo`) products, news, brand and photos modules. Remote attackers with privileged access are able to 
inject own malicious script code with persistent attack vector to compromise. The request method to inject is post and the 
attack vector is persistent. After the inject the code executes on every list preview by the admin in the backend.

Successful exploitation of the vulnerabilities results in session hijacking, persistent phishing attacks, persistent external 
redirects to malicious source and persistent manipulation of affected application modules.
