xxl-rpc v1.7.0 was discovered to contain a deserialization vulnerability via the component com.xxl.rpc.core.remoting.net.impl.netty.codec.NettyDecode#decode.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Affected Software

Name Vendor Start Version End Version
Xxl-rpc Xxl-rpc_project * 1.7.0 (including)

Potential Mitigations

  • Make fields transient to protect them from deserialization.
  • An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
