CVE detail

CVE-2021-30181

Apache Dubbo prior to 2.6.9 and 2.7.9 supports Script routing which will enable a customer to route the request to the right server. These rules are used by the customers when making a request in order to find the right endpoint. When parsing these rules, Dubbo customers use ScriptEngine and run the rule provided by the script which by default may enable executing arbitrary code.

    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.
