IBM WebSphere MQ 8.0 and 9.0 could allow a remote attacker to obtain sensitive information, caused by the failure to properly validate the SSL certificate. An attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques. IBM X-Force ID: 142598.

IBM WebSphere MQ 8.0 and 9.0, when configured to use a PAM module for authentication, could allow a user to cause a deadlock in the IBM MQ PAM code which could result in a denial of service. IBM X-Force ID: 138949.

IBM WebSphere MQ 8.0 through 8.0.0.8 and 9.0 through 9.0.4 under special circumstances could allow an authenticated user to consume all resources due to a memory leak resulting in service loss. IBM X-Force ID: 136975.

IBM WebSphere MQ 7.5.x before 7.5.0.6 and 8.0.x before 8.0.0.3 allows remote authenticated users to obtain sensitive information via a man-in-the-middle attack, related to duplication of message data in cleartext outside the protected payload. IBM X-Force ID: 103482.

IBM WebSphere MQ 7.0, 7.1, 7.5, 8.0, and 9.0 service trace module could be used to execute untrusted code under 'mqm' user. IBM X-Force ID: 132953.

IBM MQ Managed File Transfer Agent 8.0 and 9.0 sets insecure permissions on certain files it creates. A local attacker could exploit this vulnerability to modify or delete data contained in the files with an unknown impact. IBM X-Force ID: 134391.

IBM WebSphere MQ 8.0 and 9.0 could allow an authenticated user with authority to send a specially crafted request that could cause a channel process to cease processing further requests. IBM X-Force ID: 131547.

IBM WebSphere MQ 7.5, 8.0, and 9.0 could allow a local user to crash the queue manager agent thread and expose some sensitive information. IBM X-Force ID: 126454.

IBM WebSphere MQ 7.5, 8.0, and 9.0 could allow an authenticated user to insert messages with a corrupt RFH header into the channel which would cause it to restart. IBM X-Force ID: 127803.

IBM WebSphere MQ 8.0 and 9.0 could allow an authenticated user to cause a shared memory leak by MQ applications using dynamic queues, which can lead to lack of resources for other MQ applications. IBM X-Force ID: 125144.

IBM WebSphere MQ 8.0 and 9.0 could allow an authenticated user to cause a denial of service to the MQXR channel when trace is enabled. IBM X-Force ID: 121155.

IBM WebSphere MQ 8.0 could allow an authenticated user with queue manager permissions to cause a segmentation fault which would result in the box having to be rebooted to resume normal operations. IBM Reference #: 1998663.

IBM WebSphere MQ 8.0 could allow an authenticated user with authority to create a cluster object to cause a denial of service to MQ clustering. IBM Reference #: 1998647.

IBM WebSphere MQ 8.0 could allow an authenticated user with access to the queue manager to bring down MQ channels using specially crafted HTTP requests. IBM Reference #: 1998648.

IBM WebSphere MQ 8.0 could allow an authenticated user with access to the queue manager and queue, to deny service to other channels running under the same process. IBM Reference #: 1998649.

Under non-standard configurations, IBM WebSphere MQ might send password data in clear text over the network. This data could be intercepted using man in the middle techniques.

IBM WebSphere MQ 8.0 could allow an authenticated user to crash the MQ channel due to improper data conversion handling. IBM Reference #: 1998661.

IBM WebSphere MQ 7.5 before 7.5.0.7 and 8.0 before 8.0.0.5 mishandles protocol flows, which allows remote authenticated users to cause a denial of service (channel outage) by leveraging queue-manager rights.

Memory leak in queue-manager agents in IBM WebSphere MQ 8.x before 8.0.0.5 allows remote attackers to cause a denial of service (heap memory consumption) by triggering many errors.

The MQXR service in WMQ Telemetry in IBM WebSphere MQ 7.1 before 7.1.0.7, 7.5 through 7.5.0.5, and 8.0 before 8.0.0.4 uses world-readable permissions for a cleartext file containing the SSL keystore password, which allows local users to obtain sensitive information by reading this file.
