Root Cause Analysis
The vulnerability manifests in the generic invocation handling chain: 1) GenericService.$invoke
accepts attacker-controlled method parameters, 2) GenericFilter.invoke
processes these parameters using reflection and deserializes arguments via the unsafe nativejava pathway when triggered by RPC attachments. These functions appear in stack traces when malicious payloads are deserialized during exploitation. The lack of validation()
for allowed deserialization types in vulnerable versions makes these functions the critical points of exploitation.
