Description
A flaw was found in Apache MINA. An incomplete fix for a deserialization vulnerability in the AbstractIoBuffer.getObject() method allowed a static initializer in a class to be executed before the classname allowlist was applied. This could enable a remote attacker to execute arbitrary code by sending specially crafted data to an application using Apache MINA that calls IoBuffer.getObject().
