Spring Framework (versions 5.0.x prior to 5.0.7, versions 4.3.x prior to 4.3.18, and older unsupported versions) allow web applications to change the HTTP request method to any HTTP method (including TRACE) using the HiddenHttpMethodFilter in Spring MVC. If an application has a pre-existing XSS vulnerability, a malicious user (or attacker) can use this filter to escalate to an XST (Cross Site Tracing) attack.

In Apache Batik 1.x before 1.10, when deserializing subclass of `AbstractDocument`, the class takes a string from the inputStream as the class name which then use it to call the no-arg constructor of the class. Fix was to check the class type before calling newInstance in deserialization.

Spring Framework, versions 5.0 prior to 5.0.5 and versions 4.3 prior to 4.3.15 and older unsupported versions, allow applications to expose STOMP over WebSocket endpoints with a simple, in-memory STOMP broker through the spring-messaging module. A malicious user (or attacker) can craft a message to the broker that can lead to a remote code execution attack.

IBM Integration Bus 9.0 and 10.0 could allow an attacker that has captured a valid session id to hijack another users session during a small timeframe before the session times out. IBM X-Force ID: 134164.

IBM Integration Bus 9.0 and 10.0 transmits user credentials in plain in clear text which can be read by an attacker using man in the middle techniques. IBM X-Force ID: 134165.

IBM WebSphere Message Broker (IBM Integration Bus 9.0 and 10.0) could allow an unauthorized user to obtain sensitive information about software versions that could lead to further attacks. IBM X-Force ID: 121341.

IBM WebSphere Message Broker could allow a local user with specialized access to prevent the message broker from starting. IBM X-Force ID: 122033.

IBM WebSphere Message Broker stores user credentials in plain in clear text which can be read by a local user. IBM X-Force ID: 123777.

In Apache Log4j 2.x before 2.8.2, when using the TCP socket server or UDP socket server to receive serialized log events from another application, a specially crafted binary payload can be sent that, when deserialized, can execute arbitrary code.

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.
