Advisories for Maven/Org.apache.dubbo/Dubbo-Parent package

Apache Dubbo is a java based, open source RPC framework. Versions prior to 2.6.10 and 2.7.10 is vulnerable to pre-auth remote code execution via arbitrary bean manipulation in the Telnet handler. The Dubbo main service port can be used to access a Telnet Handler which offers some basic methods to collect information about the providers and methods exposed by the service and it can even allow to shutdown the service. …

A deserialization vulnerability existed in dubbo 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.
