Title

Apache Dubbo反序列化漏洞（CNVD-2021-41088）

Description

Apache Dubbo是美国阿帕奇（Apache）基金会的一款基于Java的轻量级RPC（远程过程调用）框架。该产品提供了基于接口的远程呼叫、容错和负载平衡以及自动服务注册和发现等功能。 Apache Dubbo 2.6.9和2.7.9之前存在反序列化漏洞，该漏洞源于默认支持对提供者接口公开的任意方法的通用调用。攻击者可以控制此RPC附件并将其设置为nativejava以强制对位于第三个参数中的字节数组进行java反序列化。

Title

Apache Dubbo Pre-auth RCE via Java deserialization in the Generic filter

Summary

Apache Dubbo prior to 2.6.9 and 2.7.9 by default supports generic calls to arbitrary methods exposed by provider interfaces. These invocations are handled by the GenericFilter which will find the service and method specified in the first arguments of the invocation and use the Java Reflection API to make the final call. The signature for the $invoke or $invokeAsync methods is Ljava/lang/String;[Ljava/lang/String;[Ljava/lang/Object; where the first argument is the name of the method to invoke, the second one is an array with the parameter types for the method being invoked and the third one is an array with the actual call arguments. In addition, the caller also needs to set an RPC attachment specifying that the call is a generic call and how to decode the arguments. The possible values are: - true - raw.return - nativejava - bean - protobuf-json An attacker can control this RPC attachment and set it to nativejava to force the java deserialization of the byte array located in the third argument.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
