Security Bulletin: Potential security exposures with IBM WebSphere DataPower 
XC10 Appliance (CVE-2013-0600, CVE-2013-0440, CVE-2013-0443, CVE-2013-0169)

Abstract

Document information

WebSphere DataPower XC10 Appliance

Data grids

Software version:
2.0, 2.1, 2.1.0.3

Operating system(s):
Firmware

Reference #:
1636324

Modified date:
2013-05-06

A security vulnerability has been discovered that might allow a knowledgeable 
user who has network access to a WebSphere DataPower XC10 Appliance to issue 
administrative commands without authentication. Additional vulnerabilities have
been discovered in the SSL/TLS implementations of the Java Runtime Environment 
(JRE) shipped with WebSphere DataPower XC10 Appliance.

Content

These problems affect the following versions of the WebSphere DataPower XC10 
Appliance:

WebSphere DataPower XC10 Appliance 2.0

WebSphere DataPower XC10 Appliance 2.1

Problem description:

CVE-2013-0600: This vulnerability may allow a knowledgeable user who has 
network access to a deployed WebSphere DataPower XC10 Appliance to send 
administrative operations to it without authentication. This vulnerability has 
a CVSS base score of 9.3, which indicates that it is a serious problem. If 
network access to the appliance is limited by firewalls, this limits the 
exposure associated with the vulnerability.

In addition, the Java runtime environments shipped with these levels of the 
XC10 have three vulnerabilities in the implementation of SSL/TLS. Exploiters 
must have access to the network in which the appliance is deployed, so that 
firewalls do provide protection from an external attack. Updated versions of 
the Java runtime environment as shipped with the firmware upgrades correct 
these problems too. The Java SSL/TLS vulnerabilities are described below:

CVE-2013-0440: This vulnerability might allow a partial denial of service 
attack on a WebSphere DataPower XC10 appliance configured to support SSL or 
TLS. The CVSS base score is 5.0.

CVE-2013-0443: This very difficult to exploit vulnerability might allow an 
unauthenticated attacker to gain access to a subset of data accessible to the 
XC10 appliance. The CVSS base score is 4.3.

CVE-2013-0169: This very difficult to exploit vulnerability might allow an 
unauthenticated attacker to gain access to a subset of data accessible to the 
XC10 appliance. The CVSS base score is 4.0.

Solutions:

For WebSphere DataPower XC10 Appliance 2.1 on appliance 9235-92X apply the 
Version 2.1 Fix Pack 3 firmware upgrade (APAR IC91726)

For WebSphere DataPower XC10 Appliance 2.1 on appliance 7199-92X apply the 
Version 2.1 Fix Pack 3 firmware upgrade (APAR IC91726)

WebSphere DataPower XC10 Appliance users running 2.0 versions of the firmware 
can apply one of the version 2.1 firmware upgrades.

*The CVSS Environment Score is customer environment specific and will 
ultimately impact the Overall CVSS Score. Customers can evaluate the impact of 
this vulnerability in their environments by accessing the links in the 
Reference section of this document.

Note: According to the Forum of Incident Response and Security Teams (FIRST), 
the Common Vulnerability Scoring System (CVSS) is an "industry open standard 
designed to convey vulnerability severity and help to determine urgency and 
priority of response." IBM PROVIDES THE CVSS SCORES "AS IS" WITHOUT WARRANTY OF
