===============  
1) Introduction  
===============  
  
Apache is the most common unix server in the world. It is strong and safe.  
Oracle HTTP Server is a modified, custom apache server that was created by  
apache for oracle.

2) Bug  
======  
  
The Vulnerabillity is Cross Site Scripting. If an attacker will request the  
following  
url from the server:  
http://<host>/isqlplus?action=logon&username=sdfds%22%3e%3cscript%3ealert('X  
SS')%3c/script%3e\&password=dsfsd%3cscript%3ealert('XSS')%3c/script%3e  
Or  
http://<host>/isqlplus?action=<script>alert('XSS')</script>  
XSS appears and the server allows an attacker to inject & execute scripts.  
  
In the words of securityfocus.com :  
~~~~~~~~~~~~~~~~~~~~~~~~~~  
  
If all of these circumstances are met, an attacker may be able to exploit  
this issue  
via a malicious link containing arbitrary HTML and script code as part of  
the hostname.  
When the malicious link is clicked by an unsuspecting user, the  
attacker-supplied HTML  
and script code will be executed by their web client. This will occur  
because the server  
will echo back the malicious hostname supplied in the client's request,  
without sufficiently  
escaping HTML and script code.  
  
Attacks of this nature may make it possible for attackers to manipulate web  
content or to  
steal cookie-based authentication credentials. It may be possible to take  
arbitrary actions as the victim user.
