Topic

Red Hat JBoss Data Grid 6.3.0, which fixes multiple security issues,
various bugs, and adds enhancements, is now available from the Red Hat
Customer Portal.

The Red Hat Security Response Team has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

Description

Red Hat JBoss Data Grid is a distributed in-memory data grid, based on
Infinispan.

This release of Red Hat JBoss Data Grid 6.3.0 serves as a replacement for
Red Hat JBoss Data Grid 6.2.1. It includes various bug fixes and
enhancements which are detailed in the Red Hat JBoss Data Grid 6.3.0
Release Notes. The Release Notes will be available shortly from
https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Data_Grid/

This update also fixes the following security issues:

It was discovered that JBoss Web did not limit the length of chunk sizes
when using chunked transfer encoding. A remote attacker could use this flaw
to perform a denial of service attack against JBoss Web by streaming an
unlimited quantity of data, leading to excessive consumption of server
resources. (CVE-2014-0075)

It was found that JBoss Web did not check for overflowing values when
parsing request content length headers. A remote attacker could use this
flaw to perform an HTTP request smuggling attack on a JBoss Web server
located behind a reverse proxy that processed the content length header
correctly. (CVE-2014-0099)

It was found that the security audit functionality, provided by Red Hat
JBoss Data Grid, logged request parameters in plain text. This may have
caused passwords to be included in the audit log files when using BASIC or
FORM-based authentication. A local attacker with access to audit log files
could possibly use this flaw to obtain application or server authentication
credentials. Refer to the Solution section of this advisory for additional
information on the fix for this issue. (CVE-2014-0058)

It was found that the security auditing functionality provided by PicketBox
and JBossSX, both security frameworks for Java applications, used a
world-readable audit.log file to record sensitive information. A local user
could possibly use this flaw to gain access to the sensitive information in
the audit.log file. (CVE-2014-0059)

It was found that the org.apache.catalina.servlets.DefaultServlet
implementation in JBoss Web allowed the definition of XML External Entities
(XXEs) in provided XSLTs. A malicious application could use this to
circumvent intended security restrictions to disclose sensitive
information. (CVE-2014-0096)

It was found that, in certain circumstances, it was possible for a
malicious web application to replace the XML parsers used by JBoss Web to
process XSLTs for the default servlet, JSP documents, tag library
descriptors (TLDs), and tag plug-in configuration files. The injected XML
parser(s) could then bypass the limits imposed on XML external entities
and/or gain access to the XML files processed for other web applications
deployed on the same JBoss Web instance. (CVE-2014-0119)

The CVE-2014-0075 issue was discovered by David Jorm of Red Hat Product
Security.

All users of Red Hat JBoss Data Grid 6.2.1 as provided from the Red Hat
Customer Portal are advised to upgrade to Red Hat JBoss Data Grid 6.3.0.

Solution

The References section of this erratum contains a download link (you must
log in to download the update). Before applying this update, back up your
existing JBoss Data Grid installation.

The provided patch to fix CVE-2014-0058 also allows greater control over
which of the following components of web requests are captured in audit
logs:

• parameters
• cookies
• headers
• attributes

It is also possible to selectively mask some elements of headers,
parameters, cookies, and attributes using masks. This capability is
provided by two system properties, which are introduced by this patch:

1) org.jboss.security.web.audit

Description:
This property controls the granularity of the security auditing of web
requests.

Possible values:
off = Disables auditing of web requests
headers = Audits only the headers of web requests
cookies = Audits only the cookies of web requests
parameters = Audits only the parameters of web requests
attributes = Audits only the attributes of web requests
headers,cookies,parameters = Audits the headers, cookies, and parameters of
web requests
headers,cookies = Audits the headers and cookies of web requests

Default Value:
headers, parameters

Examples:
Setting "org.jboss.security.web.audit=off" disables security auditing of
web requests entirely.
Setting "org.jboss.security.web.audit=headers" enables security auditing of
only headers in web requests.

2) org.jboss.security.web.audit.mask

Description:
This property can be used to specify a list of strings to be matched
against headers, parameters, cookies, and attributes of web requests.
Any element matching the specified masks will be excluded from security
audit logging.

Possible values:
Any comma separated string indicating keys of headers, parameters, cookies,
and attributes.

Default Value:
j_password, authorization

Note that currently the matching of the masks is fuzzy rather than strict.
For example, a mask of "authorization" will mask both the header called
authorization and the parameter called "custom_authorization". A future
release may introduce strict masks.
