Response Splitting Vulnerability found in Oracle Business Intelligence (BI Publisher Enterprise)
This vulnerability may be used as XSS or for Phishing user (PHiXSS) credentials using fake response from server
Response Splitting Vulnerability found in script /xmlpserver vulnerable parameter "_xuil"
If we send request whith CRLF sumbols in "_xuil" parameter we can generate own server request.
it is possible for an attacker to terminate the "current" response (by injecting the necessary HTTP response headers),
and then to add his/her own additional complete HTTP response.
The attacker can then orchestrate the traffic in such a way that when an additional request is sent it appears to generate the additional response.
When an attacker succeeds in sending a crafted request, and it is responded with the crafted response, there are two (perhaps more)
ways in which this condition can be exploited:
2. So when user click on link we can give him fake login page instead of XSS and steal his credentials.
