CVE-2016-4432
Description
From CVE.org
The AMQP 0-8, 0-9, 0-91, and 0-10 connection handling in Apache Qpid Java before 6.0.3 might allow remote attackers to bypass authentication and consequently perform actions via vectors related to connection state logging.
Statement
This issue did not affect the versions of the qpid -java broker as shipped with Red Hat MRG 2 and 3 and Satellite 6 as they did not use the access feature (e.g. Satellite 6 relies on client certificate authentication to control access).
Mitigation
If upgrading is not possible, the vulnerability can be mitigated using
an ACL file containing "ACCESS VIRTUALHOST" clauses that white-lists
user access to all virtualhosts.
If AMQP 0-8, 0-9, 0-91, and 0-10 support is not required, the
vulnerability can also be mitigated by turning off these protocols at
the Port level.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
