Apache Qpid Broker-J Multiple Vulnerabilities
1 December 2017
===========================================================================
AusCERT Security Bulletin Summary
---------------------------------
Product: Apache Qpid Broker-J
Publisher: The Apache Software Foundation
Operating System: UNIX variants (UNIX, Linux, OSX)
Windows
Impact/Access: Denial of Service -- Remote/Unauthenticated
Provide Misleading Information -- Existing Account
Resolution: Patch/Upgrade
CVE Names: CVE-2017-15702 CVE-2017-15701
Original Bulletin:
https://issues.apache.org/jira/browse/QPID-8039
Comment: This bulletin contains two (2) The Apache Software Foundation
security advisories.
- --------------------------BEGIN INCLUDED TEXT--------------------
CVE-2017-15701: Apache Qpid Broker-J denial of service vulnerability
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: 6.1.0, 6.1.1, 6.1.2, 6.1.3, and 6.1.4
Description:
The broker does not properly enforce a maximum frame size in AMQP 1.0
frames. A remote unauthenticated attacker could exploit this to cause
the broker to exhaust all available memory and eventually terminate.
Older AMQP protocols are not affected.
Resolution:
Users who have AMQP 1.0 support enabled (default) should upgrade their
Qpid Broker-J to version 6.1.5 or later.
Mitigation:
If upgrading the broker is not possible, users can choose to disable
AMQP 1.0 by either setting the system property
"qpid.plugin.disabled:protocolenginecreator.AMQP_1_0" to "true",
excluding "AMQP_1_0" from the supported protocol list on all AMQP
ports, or by removing the AMQP 1.0 related jar files from the Java
classpath.

- ------------------------------------------------------------------------
CVE-2017-15702: Apache Qpid Broker-J authentication vulnerability on HTTP ports
Severity: Important
Vendor: The Apache Software Foundation
Versions Affected: Versions 0.18 through 0.32
Description:
If the broker is configured with different authentication providers on
different ports one of which is an HTTP port, then the broker can be
tricked by a remote unauthenticated attacker connecting to the HTTP
port into using an authentication provider that was configured on a
different port. The attacker still needs valid credentials with the
authentication provider on the spoofed port. This becomes an issue
when the spoofed port has weaker authentication protection (e.g.,
anonymous access, default accounts) and is normally protected by
firewall rules or similar which can be circumvented by this
vulnerability. AMQP ports are not affected. Versions 6.0.0 and newer
are not affected.
Resolution:
Users of affected versions who have more than one port and different
authentication providers configured on them should upgrade to a
later unaffected version.
Mitigation:
If upgrading the broker is not possible then users should ensure all
their authentication providers offer an equal amount of protection.
In particular, authentication providers with default accounts and
those with anonymous access should be removed if other providers in
use require credentials.
