IBM WebSphere Application Server contains multiple vulnerabilities

Overview

IBM WebSphere Application Server, including the Hypervisor Edition, contains cross-site scripting and cross-site request forgery vulnerabilities.

Description

CWE-79: Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’) - CVE-2014-4770

IBM WebSphere Application Server, including the Hypervisor Edition, contains a cross-site scripting (XSS) vulnerability in the Administrative Console.

CWE-352: Cross-Site Request Forgery (CSRF) - CVE-2014-4816
IBM WebSphere Application Server, including the Hypervisor Edition, contains a cross-site request forgery (CSRF) vulnerability in the Administrative Console. The application also provides a URL that allows authenticated users to directly create and modify their session variables (“Session Injection”), including CSRF tokens.

IBM reports that the following versions are affected:

* Version 8.5 
* Version 8
* Version 7
* Version 6.1 
* Version 6.0.2

The CVSS score reflects CVE-2014-4770.

Impact

A remote unauthenticated attacker may be able to execute arbitrary script in the context of the end-user’s browser session. Additionally, a remote unauthenticated attacker may be able to trick an authenticated user into making an unintentional request to the web server which will be treated as an authentic request and may result in information leakage or modification.
