CVE-2023-46604

Apache ActiveMQ es vulnerable a la ejecución remota de código. La vulnerabilidad puede permitir que un atacante remoto con acceso a la red de un corredor ejecute comandos de shell arbitrarios manipulando tipos de clases serializadas en el protocolo OpenWire para hacer que el corredor cree una instancia de cualquier clase en el classpath. Se recomienda a los usuarios actualizar a la versión 5.15.16, 5.16.7, 5.17.6 o 5.18.3, que soluciona este problema.

A flaw was found in Apache ActiveMQ, specifically the OpenWire Module. This flaw may allow a remote malicious user to run arbitrary shell commands by manipulating serialized class types in the OpenWire protocol, causing the broker to instantiate any class on the classpath. This issue happens when OpenWire commands are unmarshalled, without validating the provided throwable class type, which could allow an attacker to jeopardize the entire server.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Delta Electronics InfraSuite Device Master. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the Apache ActiveMQ broker, which listens on TCP port 61616 by default. The issue results from the use of a vulnerable version of Apache ActiveMQ. An attacker can leverage this vulnerability to execute code in the context of the service account.

Apache ActiveMQ contains a deserialization of untrusted data vulnerability that may allow a remote attacker with network access to a broker to run shell commands by manipulating serialized class types in the OpenWire protocol to cause the broker to instantiate any class on the classpath.
