CVE detail

CVE-2020-11995

A deserialization vulnerability existed in dubbo 2.7.5 and its earlier versions, which could lead to malicious code execution. Most Dubbo users use Hessian2 as the default serialization/deserialization protool, during Hessian2 deserializing the HashMap object, some functions in the classes stored in HasMap will be executed after a series of program calls, however, those special functions may cause remote command execution. For example, the hashCode() function of the EqualsBean class in rome-1.7.0.jar will cause the remotely load malicious classes and execute malicious code by constructing a malicious request. This issue was fixed in Apache Dubbo 2.6.9 and 2.7.8.

  • Apache Dubbo: All roads lead to RCEGitHub Security Lab

    During an audit of Apache Dubbo v2.7.8 source code, I found multiple vulnerabilities enabling attackers to compromise and run arbitrary system commands on both Dubbo consumers and providers. In this blog post I detailed how I leveraged CodeQL as an audit oracle to help me find these issues.
