(RHSA-2013:0533) Important: JBoss Enterprise SOA Platform 5.3.1 update

Security:

JBoss Web Services leaked side-channel data when distributing symmetric
keys (for XML encryption), allowing a remote attacker to recover the entire
plain text form of a symmetric key. (CVE-2011-2487)

Spring framework could possibly evaluate Expression Language (EL)
expressions twice, allowing a remote attacker to execute arbitrary code in
the context of the application server, or to obtain sensitive information
from the server. (CVE-2011-2730)

Note: Manual action is required to apply the fix for CVE-2011-2730. If your
system has deployed applications which use Spring framework, the context
parameter “springJspExpressionSupport” must be set to “false” to mitigate
this flaw, for example, in the application’s web.xml file. This will
prevent the double-evaluation of EL expressions that led to this flaw.

An XSS flaw allowed a remote attacker to perform an XSS attack against
victims using the JMX Console. (CVE-2011-4575)

SecurityAssociation.getCredential() returned the previous credential if
no security context was provided. Depending on the deployed applications,
this could possibly allow a remote attacker to hijack the credentials of a
previously-authenticated user. (CVE-2012-3370)

A denial of service flaw was found in the implementation of associative
arrays (hashes) in JRuby. An attacker able to supply a large number of
inputs to a JRuby application (such as HTTP POST request parameters sent to
a web application) that are used as keys when inserting data into an array
could trigger multiple hash function collisions, making array operations
take an excessive amount of CPU time. To mitigate this issue, the Murmur
hash function has been replaced with the Perl hash function.
(CVE-2012-5370)

Note: JBoss Enterprise SOA Platform only provides JRuby as a dependency of
the scripting_chain quickstart example application. The CVE-2012-5370 flaw
is not exposed unless the version of JRuby shipped with that quickstart is
used by a deployed, custom application.

Configuring the JMX Invoker to restrict access to users with specific
roles did not actually restrict access, allowing remote attackers with
valid JMX Invoker credentials to perform JMX operations accessible to
roles they are not a member of. (CVE-2012-5478)

twiddle.sh accepted credentials as command line arguments, allowing local
users to view them via a process listing. (CVE-2009-5066)

NonManagedConnectionFactory logged the username and password in plain text
when an exception was thrown. This could lead to the exposure of
authentication credentials if local users had permissions to read the log
file. (CVE-2012-0034)

The JMXInvokerHAServlet and EJBInvokerHAServlet invoker servlets allow
unauthenticated access by default in some profiles. The security
interceptor’s second layer of authentication prevented direct exploitation
of this flaw. If the interceptor was misconfigured or inadvertently
disabled, this flaw could lead to arbitrary code execution in the context
of the user running the JBoss server. (CVE-2012-0874)

CallerIdentityLoginModule retained the password from the previous call if a
null password was provided. In non-default configurations this could
possibly lead to a remote attacker hijacking a previously-authenticated
user’s session. (CVE-2012-3369)

Red Hat would like to thank Juraj Somorovsky of Ruhr-University Bochum
for reporting CVE-2011-2487, and Tyler Krpata for reporting CVE-2011-4575.
The CVE-2012-3370 and CVE-2012-3369 issues were discovered by Carlo de Wolf
of Red Hat; CVE-2012-5478 was discovered by Derek Horton of Red Hat; and
CVE-2012-0874 was discovered by David Jorm of the Red Hat Security Response
Team.

Warning: Before applying the update, back up your existing JBoss Enterprise
SOA Platform installation (including its databases, applications,
configuration files, and so on).

All users of JBoss Enterprise SOA Platform 5.3.0 as provided from the Red
Hat Customer Portal are advised to upgrade to JBoss Enterprise SOA Platform
5.3.1.
