Title: DCP-Portal Multiple XSS Vulnerabilities
Vendor: Worxware
Product: DCP-Portal
Tested Version: 7.0beta
Threat Class: XSS
Severity: High
Remote: yes
Local: no
Discovered By: Andrei Rimsa Alvares

===== Description =====

Multiple XSS vulnerabilities found in the DCP-Portal.

1. common/components/editor/insert_image.php, modules/newsletter/insert_image.php, php/editor.php
  The variable $upload_failure_report gets user input from http get request variable "Image" when the action of 
deleting an uploaded file fails. Later this variable is outputted to the page without proper sanitization.

2. modules/gallery/view_img.php
  Page title can be modified by changing the http request variable "imgtitle". Since no sanitizer is used, an XSS 
occurs on line 2.
  Another vulnerability exists if magic quotes is turned off. The http request variable "imagename" gets outputted on 
the java script function document.write between simple quotes on line 27.

3. modules/tips/show_tip.php
  Http request variable "newsId" gets outputted to the page without proper sanitization on line 14.

===== Impact =====

Malicious java script code can be executed in the context of the affected web site.

All proof of concepts display a java script alert containing the message "XSS".
