CVSS vector description

Metric	Value	Metric Description	Value Description
Attack vector	Network	AV	The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity	Low	AC	The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required	None	PR	The attacker is unauthenticated prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
Scope		S	An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
Confidentiality	Low	C	There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity	Low	I	Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system.
Availability	Low	A	There is reduced performance or interruptions in resource availability. However, the attacker does not have the ability to completely prevent access to the resources or services; the impact is limited.

SEC Consult Security Advisory < 20051223-0 > ======================================================================== title: < Multiple Cross Site Scripting Vulnerabilities in OracleAS Discussion Forum Portlet > program: < OracleAS Discussion Forum Portlet > vulnerable version: < Version of May 2005 > homepage: < http://www.oracle.com > found: < 2005-09-16 > by: < Johannes Greil > SEC Consult / www.sec-consult.com ======================================================================== 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. [www.oracle.com] 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. e.g. http://$host/portal/page?_pageid=XXX,XXX&_dad=portal&_schema=PORTAL& df_next_page=htdocs/forums.jsp& RowKeyValue=<script>alert(document.cookie)</script> 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: <script>document.write(document.cookie)</script> vulnerable versions: -------------------- Version of May 2005 http://www.oracle.com/technology/products/ias/portal/point_downloads.html#forum 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. solution: --------- Only use the forum portlet in test installations and not in a production environment. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ < Johannes Greil > SEC Consult / www.sec-consult.com SGT ::: < tke, mei, bmu, dfa > :::
