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 to crash the MQ channel due to improper data conversion handling. IBM Reference #: 1998661.

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 Integration Bus 9.0 and 10.0 and WebSphere Message Broker SOAP FLOWS is vulnerable to a denial of service, caused by an XML External Entity Injection (XXE) error when processing XML data. A remote attacker could exploit this vulnerability to expose highly sensitive information or consume all available memory resources. IBM Reference #: 1997918.

IBM Websphere MQ JMS 7.0.1, 7.1, 7.5, 8.0, and 9.0 client provides classes that deserialize objects from untrusted sources which could allow a malicious user to execute arbitrary Java code by adding vulnerable classes to the classpath. IBM Reference #: 1983457.

IBM WebSphere Message Broker 9.0 and 10.0 could allow a remote attacker to hijack the clicking action of the victim. By persuading a victim to visit a malicious Web site, a remote attacker could exploit this vulnerability to hijack the victim's click actions and possibly launch further attacks against the victim. IBM Reference #: 1997906.

IBM WebSphere Application Server 7.0, 8.0, and 9.0 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM Reference #: 1997743

IBM WebSphere eXtreme Scale and the WebSphere DataPower XC10 Appliance allow some sensitive data to linger in memory instead of being overwritten which could allow a local user with administrator privileges to obtain sensitive information.
