Security Bulletin
Summary
There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition, Versions 6 and 7 that are used by WebSphere DataPower XC10 Appliance.
These issues were disclosed as part of the IBM Java SDK updates in January
2016 and includes the vulnerability commonly referred to as SLOTH.
Vulnerability Details
CVEID: CVE-2016-0475
DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded
and Jrockit related to the Libraries component has partial confidentiality
impact, partial integrity impact, and no availability impact.
CVSS Base Score: 5.8
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109946 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)
CVEID: CVE-2015-7575
DESCRIPTION: The TLS protocol could allow weaker than expected security caused
by a collision attack when using the MD5 hash function for signing a
ServerKeyExchange message during a TLS handshake. An attacker could exploit
this vulnerability using man-in-the-middle techniques to impersonate a TLS
server and obtain credentials. This vulnerability is commonly referred to as
SLOTH.
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)
CVEID: CVE-2016-0448
DESCRIPTION: An unspecified vulnerability in Oracle Java SE and Java SE
Embedded related to the JMX component could allow a remote attacker to obtain
sensitive information resulting in a partial confidentiality impact using
unknown attack vectors.
CVSS Base Score: 4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current
score
CVSS Environmental Score*: Undefined

Affected Products and Versions
WebSphere DataPower XC10 Appliance Version 2.1
WebSphere DataPower XC10 Appliance Version 2.5
Remediation/Fixes
Apply an interim fix, according to the table below. Interim fixes are
associated with the original APAR that is documented in the table. Because
these APAR references might be updated to more recent APARs, see the links in
the table for the most recent interim fix information.
This interim fix contains a new default SSL certificate, as the previous
default SSL certificate, which was never intended for production use, has an
MD5 signature and is no longer compatible with Java. The result is that
installing this interim fix will make it incompatible with any WebSphere
Datapower XC10 appliances that are running with an MD5 certificate, including
the default SSL certificate that was shipped prior to this interim fix. If the
appliance is configured with a custom keystore and certificate with an MD5
signature, it must be replaced prior to upgrading to this interim fix or the
'clear-tls-config' command must be run on the appliance before or after
performing the upgrade. Failing to do so will result in the appliance failing
to start. Note that changing the active certificate for an appliance
collective does require that the cache be reloaded and client truststores must
be configured to trust the new certificate.
Product Version APAR Link to interim fix
WebSphere DataPower XC10 Appliance 2.1 IT13446 Refer to the Version 2.1 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
V2.1 on appliance 9235-92X
WebSphere DataPower XC10 Appliance 2.1 IT13446 Refer to the Version 2.1 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
V2.1 on appliance 7199-92X
WebSphere DataPower XC10 Appliance Version 2.5 with IT13446 Refer to the Version 2.5 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
V2.5 on appliance 7199-92X SSD drivers
Important: See More Information
link and follow instructions to
determine if you have an old or
newer SSD driver on your appliance
using the show ssd-version command.
WebSphere DataPower XC10 Appliance 2.5 IT13446 Refer to the Version 2.5 table in Recommended fixes for WebSphere DataPower XC10 Appliance.
V2.5 virtual image
Workarounds and Mitigations
There is no workaround. The interim fix must be applied to correct the
problem.
