Apache Syncope Remote Code Execution Vulnerability in Scripted Connectors

Vulnerability

A remote code execution vulnerability has been identified in Apache Syncope versions 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.6, and 4.1.0-M0 through 4.1.1. This vulnerability arises from improper isolation in the connector subsystem, allowing an administrator with sufficient entitlements to execute arbitrary code by leveraging the capability of scripted connectors (REST and SQL) to run Groovy scripts.

Impact

Exploitation of this vulnerability allows for remote code execution on the server where Apache Syncope is running.

Remediation

Users are advised to upgrade to Apache Syncope versions 4.0.7 or 4.1.2, which address this vulnerability by enhancing the security sandbox for Groovy scripts.
