Executive brief
Apache Syncope, an open-source system for managing digital identities, contains a security flaw that could allow an authorized administrator to execute unauthorized code on the server. By exploiting the way the system handles database and web service connections, a user with administrative privileges can bypass security restrictions to run custom scripts. This could lead to a full system takeover, data theft, or disruption of identity management services.
Technical details
An improper isolation vulnerability (CWE-653) exists in Apache Syncope's connector subsystem. The vulnerability allows an administrator with sufficient entitlements to bypass the Groovy security sandbox when using scripted REST or SQL connectors. By providing malicious Groovy scripts through these connectors, an attacker can achieve remote code execution (RCE) on the underlying host. The issue is addressed in versions 4.0.7 and 4.1.2 by hardening the Groovy security sandbox to prevent unauthorized script execution.
