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.
