Deserialization of Untrusted Data Affecting org.apache.camel:camel-mina package, versions [3.0.0-M1,4.14.6)[4.15.0,4.18.2)[4.19.0,4.20.0)
Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

Overview
Affected versions of this package are vulnerable to Deserialization of Untrusted Data via the MinaConverter.toObjectInput() function. An attacker can execute arbitrary code by sending a crafted serialized Java object over the network to the MINA TCP or UDP consumer port when conversion to ObjectInput is requested.
Details
Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.
Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
