CVE-2024-52046: Apache MINA: MINA applications using unbounded deserialization may allow RCE

10.0 CVSS

Description

The ObjectSerializationDecoder in Apache MINA uses Java’s native deserialization protocol to process
incoming serialized data but lacks the necessary security checks and defenses. This vulnerability allows
attackers to exploit the deserialization process by sending specially crafted malicious serialized data,
potentially leading to remote code execution (RCE) attacks.


This issue affects MINA core versions 2.0.X, 2.1.X and 2.2.X, and will be fixed by the releases 2.0.27, 2.1.10 and 2.2.4.

It's also important to note that an application using MINA core library will only be affected if the IoBuffer#getObject() method is called, and this specific method is potentially called when adding a ProtocolCodecFilter instance using the ObjectSerializationCodecFactory class in the filter chain. If your application is specifically using those classes, you have to upgrade to the latest version of MINA core library.

Upgrading will  not be enough: you also need to explicitly allow the classes the decoder will accept in the ObjectSerializationDecoder instance, using one of the three new methods:

/**

     * Accept class names where the supplied ClassNameMatcher matches for

* deserialization, unless they are otherwise rejected.

*

* @param classNameMatcher the matcher to use

*/

public void accept(ClassNameMatcher classNameMatcher)

/**

* Accept class names that match the supplied patte...
