vendor description:


Oracle's business is information - how to manage it, use it, share it,

protect it. For nearly three decades, Oracle, the world's largest

enterprise software company, has provided the software and services that

let organizations get the most up-to-date and accurate information from

their business systems.




vulnerability overview:



The discussion forum portlet suffers from multiple Cross Site Scripting

vulnerabilities. E.g. it is possible to create relogin trojans, steal

session cookies, alter the content of the site or hide articles which

don't show up in the overview page.


1) The URL parameter "RowKeyValue" is not properly validated and is

prone to Cross Site Scripting. It gets a problem if one can trick a user

to click a malicious link.


2) A more severe Cross Site Scripting problem exists in all input fields

of the forum when posting an article. Those fields aren't filtered at

all and it is possible to insert malicious code.



proof of concept:


1) By requesting the forum URL and adding scripting code to the

"RowKeyValue" parameter it is possible to trigger a temporary XSS bug

via a URL.



http: // $host/portal/page?_pageid=XXX,XXX&_dad=portal&_schema=PORTAL&


2) It is possible to launch a permanent XSS attack by storing the

scripting code in a forum article. A regular user only needs to view

such an article to have her/his account data stolen without

any other interaction. If an attacker hides the article via

specially crafted title content, only viewing the overview page is

enough to execute malicious code.


e.g. add scripting code in title or content input field of an article:




vulnerable versions:



Version of May 2005



vendor status:


vendor notified: 2005-09-26

vendor response: 2005-09-27

patch available: -


The first response from Oracle was on 27th September (assigning bug

numbers) with a more detailed answer on 28th September. They explicitly

said that the forum is sample code and shouldn't be used in a production

environment although it can be found in such installations.


The last email from Oracle was on 21st October saying that they will fix

it "hopefully within the next 4 weeks". Asking them for a status update

at the beginning of December and another email on 19th December didn't

trigger any responses hence this advisory is being released.






Only use the forum portlet in test installations and not in a production
