IBM MQ Light before 1.0.0.2 allows remote attackers to cause a denial of service (CPU consumption) via a crafted byte sequence in authentication data.

MQ Explorer in IBM WebSphere MQ before 8.0.0.3 does not recognize the absence of the compatibility-mode option, which allows remote attackers to obtain sensitive information by sniffing the network for a session in which TLS is not used.

IBM WebSphere Message Broker Toolkit 7 before 7007 IF2 and 8 before 8005 IF1 and Integration Toolkit 9 before 9003 IF1 are distributed with MQ client JAR files that support only weak TLS ciphers, which might make it easier for remote attackers to obtain sensitive information by sniffing the network during a connection to an Integration Bus node.

The HTTP connection-management functionality in Internet Pass-Thru (IPT) before 2.1.0.2 in IBM WebSphere MQ, when HTTPS is disabled, does not properly generate MQIPT Session IDs, which makes it easier for remote attackers to bypass intended restrictions on MQ message data by predicting an ID value.

The cluster repository manager in IBM WebSphere MQ 7.5 before 7.5.0.5 and 8.0 before 8.0.0.2 allows remote authenticated administrators to cause a denial of service (memory overwrite and daemon outage) by triggering multiple transmit-queue records.

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.

IBM WebSphere MQ classes for Java libraries 8.0 before 8.0.0.1 and Websphere MQ Explorer 7.5 before 7.5.0.5 and 8.0 before 8.0.0.2 allow local users to discover preconfigured cleartext passwords via an unspecified trace operation.

IBM WebSphere MQ 8.x before 8.0.0.1 does not properly enforce CHLAUTH rules for blocking client connections in certain circumstances related to the CONNAUTH attribute, which allows remote authenticated users to bypass intended queue-manager access restrictions via unspecified vectors.

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.

IBM MessageSight 1.x before 1.1.0.0-IBM-IMA-IT01015 allows remote attackers to cause a denial of service (daemon restart) via crafted MQ Telemetry Transport (MQTT) authentication data.

IBM MessageSight 1.x before 1.1.0.0-IBM-IMA-IT01015 allows remote attackers to cause a denial of service (resource consumption) via WebSockets MQ Telemetry Transport (MQTT) data.

The command-port listener in IBM WebSphere MQ Internet Pass-Thru (MQIPT) 2.x before 2.1.0.1 allows remote attackers to cause a denial of service (remote-administration outage) via unspecified vectors.

Directory traversal vulnerability in WMQ Telemetry in IBM WebSphere MQ 7.5 before 7.5.0.3 allows remote attackers to read arbitrary files via a crafted URI.

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.

IBM WebSphere MQ 7.1, when an SVRCONN channel is used, allows remote attackers to bypass the security-configuration setup step and obtain queue-manager access via unspecified vectors.

Multiple cross-site request forgery (CSRF) vulnerabilities in the Web Gateway component in IBM WebSphere MQ File Transfer Edition 7.0.4 and earlier, and WebSphere MQ - Managed File Transfer 7.5, allow remote attackers to hijack the authentication of arbitrary users for requests that (1) add user accounts via the /wmqfteconsole/Filespaces URI, (2) modify permissions via the /wmqfteconsole/FileSpacePermisssions URI, or (3) add MQ Message Descriptor (MQMD) user accounts via the /wmqfteconsole/UploadUsers URI.

The Web Gateway component in IBM WebSphere MQ File Transfer Edition 7.0.4 and earlier allows remote authenticated users to read files of arbitrary users via vectors involving a username in a URI, as demonstrated by a modified metadata=fteSamplesUser field to the /transfer URI.

IBM WebSphere MQ 6.0 on OpenVMS, when the default rights of the MQM group are established, does not properly verify User Authorization File (UAF) data, which allows local users to kill listener processes and the command server via a control command.
