CVE-2020-5413 Information

Description

Spring Integration framework provides Kryo Codec implementations as an alternative for Java (de)serialization. When Kryo is configured with default options all unregistered classes are resolved on demand. This leads to the \deserialization gadgets\ exploit when provided data contains malicious code for execution during deserialization. In order to protect against this type of attack Kryo can be configured to require a set of trusted classes for (de)serialization. Spring Integration should be proactive against blocking unknown \deserialization gadgets\ when configuring Kryo in code.
