Apache Syncope versions 3.0.0-M0 through 3.0.16 and 4.0.0-M0 through 4.1.1 are vulnerable to an improper isolation issue that allows an authenticated administrator to import and execute arbitrary BPMN process definitions containing Groovy scripts via the REST API. This can lead to arbitrary code execution on the server, posing a critical security risk. Organizations using affected versions should prioritize upgrading to 4.0.7 or 4.1.2 to mitigate this vulnerability.

Original NVD Description

Improper Isolation or Compartmentalization vulnerability in Apache Syncope. 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. 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. Users are recommended to upgrade to version 4.0.7 / 4.1.2, which fix this issue by wrapping Flowable's Groovy scriptTasks with security sandbox.
