Overview

AI description

Automated description summarized from trusted sources.

CVE-2023-46604 is a remote code execution (RCE) vulnerability that affects Apache ActiveMQ. It stems from the Java OpenWire protocol marshaller. A remote attacker with network access to a Java-based OpenWire broker or client can exploit this vulnerability. By manipulating serialized class types in the OpenWire protocol, the attacker can cause the broker or client to instantiate any class on the classpath, potentially leading to the execution of arbitrary shell commands. It is recommended to upgrade both brokers and clients to version 5.15.16, 5.16.7, 5.17.6, or 5.18.3 to address this issue.

Description
