CVE-2024-23636: Remote Command Execution in SOFARPC
Impact 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 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.

Patches Fixed this issue by adding a blacklist, users can upgrade to sofarpc version 5.12.0 to avoid this issue.
Workarounds SOFARPC also provides a way to add additional blacklist. Users can add some class like -Drpc_serialize_blacklist_override=org.apache.xpath. to avoid this issue.
