CVE-2024-23636 Information

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.
