Action required by CISAfederal deadline: 2023-11-23
Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
Researched and written with AI from the vendor advisory and public analysis, with the sources above. Always confirm the fixed version in the official advisory before acting.
The Java OpenWire protocol marshaller is vulnerable to Remote Code
Execution. This vulnerability may allow a remote attacker with network
access to either a Java-based OpenWire broker or client to run arbitrary
shell commands by manipulating serialized class types in the OpenWire
protocol to cause either the client or the broker (respectively) to
instantiate any class on the classpath.
Users are recommended to upgrade
both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3
which fixes this issue.
