CVE-2021-32647

Summary

Emissary is a P2P based data-driven workflow engine. Affected versions of Emissary are vulnerable to post-authentication Remote Code Execution (RCE). The CreatePlace REST endpoint accepts an sppClassName parameter which is used to load an arbitrary class. This class is later instantiated using a constructor with the following signature: <constructor>(String, String, String). An attacker may find a gadget (class) in the application classpath that could be used to achieve Remote Code Execution (RCE) or disrupt the application. Even though the chances to find a gadget (class) that allow arbitrary code execution are low, an attacker can still find gadgets that could potentially crash the application or leak sensitive data. As a work around disable network access to Emissary from untrusted sources.
