DescriptionNVD

The fix for CVE-2024-52046 in Apache MINA AbstractIoBuffer.getObject() was incomplete. The classname allowlist of classes allowed to be deserialized was applied too late after a static initializer in a class to be read might already have been executed.

Affected versions are Apache MINA 2.0.0 <= 2.0.27, 2.1.0 <= 2.1.10, and 2.2.0 <= 2.2.5.

The problem is resolved in Apache MINA 2.0.28, 2.1.11, and 2.2.6 by applying the classname allowlist earlier.

Affected are applications using Apache MINA that call IoBuffer.getObject().

Applications using Apache MINA are advised to upgrade

AnalysisAI

Remote unauthenticated attackers can execute arbitrary code in Apache MINA 2.0.0-2.0.27, 2.1.0-2.1.10, and 2.2.0-2.2.5 through unsafe deserialization in AbstractIoBuffer.getObject(). This is an incomplete fix bypass for CVE-2024-52046 where the classname allowlist validation occurs after static initializers execute, enabling attackers to trigger malicious code execution before security controls engage. …
