IBM WebSphere MQ 7.1 is vulnerable to a denial of service, caused by an error when handling user ids. A remote attacker could exploit this vulnerability to bypass the security configuration setup on a SVRCONN channel and flood the queue manager.
IBM MQ and MQ Appliance 7.1, 7.5, 8.0, 9.0 LTS, 9.1 LTS, and 9.1 C are vulnerable to a denial of service attack due to an error within the Data Conversion logic. IBM X-Force ID: 177081.
An IBM WebSphere MQ (Maintenance levels 7.1.0.0 - 7.1.0.9, 7.5.0.0 - 7.5.0.8, 8.0.0.0 - 8.0.0.8, 9.0.0.0 - 9.0.0.2, and 9.0.0 - 9.0.4) client connecting to a Queue Manager could cause a SIGSEGV in the Channel process amqrmppa. IBM X-Force ID: 137775.
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.
Cross-site scripting (XSS) vulnerability in MQ XR WebSockets Listener in WMQ Telemetry in IBM WebSphere MQ 8.0 before 8.0.0.2 allows remote attackers to inject arbitrary web script or HTML via a crafted URI that is included in an error response.
IBM WebSphere MQ 7.0.1 before 7.0.1.13, 7.1 before 7.1.0.6, 7.5 before 7.5.0.5, and 8 before 8.0.0.1 allows remote authenticated users to cause a denial of service (queue-slot exhaustion) by leveraging PCF query privileges for a crafted query.
inetd in IBM WebSphere MQ 7.1.x before 7.1.0.5 and 7.5.x before 7.5.0.4 allows remote attackers to cause a denial of service (disk or CPU consumption) via unspecified vectors.
Multiple buffer overflows in mqm programs in IBM WebSphere MQ 7.0.x before 7.0.1.11, 7.1.x before 7.1.0.3, and 7.5.x before 7.5.0.2 on non-Windows platforms allow local users to gain privileges via unspecified vectors.
The server message channel agent in the queue manager in the server in IBM WebSphere MQ 7.0.1 before 7.0.1.9, 7.1, and 7.5 on Solaris allows remote attackers to cause a denial of service (invalid address alignment exception and daemon crash) via vectors involving a multiplexed channel.
