Description

SOFARPC is a Java RPC framework. SOFARPC defaults to using the SOFA Hessian protocol to deserialize received data, while the SOFA Hessian protocol uses a blacklist mechanism to restrict deserialization of potentially dangerous classes for security protection. But, prior to version 5.12.0, there is a gadget chain that can bypass the SOFA Hessian blacklist protection mechanism, and this gadget chain only relies on JDK and does not rely on any third-party components. Version 5.12.0 fixed this issue by adding a blacklist. SOFARPC also provides a way to add additional blacklists. Users can add a class like `-Drpc_serialize_blacklist_override=org.apache.xpath.` to avoid this issue.
