Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection')
CVE-2024-46983
Summary
The sofa-hessian is an internal improved version of Hessian3/4 powered by Ant Group CO., Ltd. 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. This issue is fixed by an update to the blacklist, users can upgrade to avoid this issue. Users unable to upgrade may maintain a blacklist themselves in the directory "external/serialize.blacklist". This issue affects com.alipay.sofa:hessian versions through 3.5.4 and 4.0.0 through 4.0.4.
