Background
Apache Synapse is an open-source Enterprise Service Bus (ESB) that provides a lightweight mediation framework for routing, transforming, and orchestrating messages between different systems. It is widely used in enterprise environments to enable seamless integration between various applications and services. However, a vulnerability has been discovered in Apache Synapse versions 3.0.1 and earlier, which allows for remote code execution attacks through the injection of specially crafted serialized objects. This vulnerability is particularly critical when the distribution includes Apache Commons Collections 3.2.1 or previous versions.
Vulnerability Detail
The vulnerability in Apache Synapse arises from the lack of authentication required for Java Remote Method Invocation (RMI) by default. This allows an attacker to exploit the system by injecting malicious serialized objects. When the affected version of Apache Commons Collections (3.2.1 or earlier) is present in the Synapse distribution, the vulnerability becomes exploitable. Successful exploitation of this vulnerability can lead to remote code execution, enabling an attacker to execute arbitrary commands on the target system. To mitigate this issue, it is recommended to limit RMI access to trusted users and upgrade to version 3.0.1, which includes an updated version of Apache Commons Collections (3.2.2).

FAQ
Apache Synapse is an open-source Enterprise Service Bus (ESB) that provides a lightweight mediation framework for routing, transforming, and orchestrating messages between different systems.
Java Remote Method Invocation (RMI) is a Java API that allows an object running in one Java Virtual Machine (JVM) to invoke methods on an object running in another JVM, as if it were local.
Apache Commons Collections is a library that provides additional collection classes and utilities for Java. It includes various data structures and algorithms to enhance the functionality of Java collections.
The vulnerability allows for remote code execution, which means an attacker can execute arbitrary commands on the target system. This can lead to unauthorized access, data theft, system compromise, and other malicious activities.
To mitigate this vulnerability, it is recommended to limit RMI access to trusted users and upgrade Apache Synapse to version 3.0.1 or later, which includes the updated version of Apache Commons Collections (3.2.2).
