Description
Improper Isolation or Compartmentalization vulnerability in Apache Syncope.<br />
<br />
An administrator with adequate entitlements can import arbitrary BPMN process definitions via the REST API and then start the process. When a BPMN process containing a Groovy scriptTask is imported and started, the Groovy script is executed directly on the server, with no sandbox.<br />
<br />
<br />
This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 Through 4.0.6, from 4.1.0-M0 through 4.1.1.<br />
<br />
<br />
<br />
<br />
Users are recommended to upgrade to version 4.0.7 / 4.1.2, which fix this issue by wrapping Flowable&#39;s Groovy scriptTasks with security sandbox.
