Risk Score
83
The Java OpenWire protocol is associated with the open source message-oriented broker service, Apache ActiveMQ, which enables client connections. A vulnerability in the Java OpenWire protocol enables remote attackers to manipulate a serialized class type and inject malicious commands. To exploit this vulnerability, the attacker establishes a connection to ActiveMQ over the OpenWire protocol and sends a specially designed OpenWire request. The ActiveMQ server trusts the class type provided by the attacker. Then, the request prompts the ActiveMQ server to load a class configuration file and run the malicious command within the serialized class type.
Upgrade brokers and clients to version 5.18.3, 5.17.6, 5.16.7, or 5.15.16
