SOFA Hessian Remote Command Execution (RCE) Vulnerability

Impact

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 update blacklist, users can upgrade to sofahessian version 3.5.5 to avoid this issue.

Workarounds

You can maintain a blacklist yourself in this directory external/serialize.blacklist.
