CVE-2025-57738: Apache Syncope: Remote Code Execution by delegated
administrators

Severity: moderate 

Affected versions:

- Apache Syncope 2.1 through 2.1.14
- Apache Syncope 3.0 through 3.0.13
- Apache Syncope 4.0 through 4.0.1


Description:

Apache Syncope offers the ability to extend / customize the base
behavior on every deployment by allowing to provide custom
implementations of a few Java interfaces; such implementations can
be provided either as Java or Groovy classes, with the latter being
particularly attractive as the machinery is set for runtime reload.
Such a feature has been available for a while, but recently it was
discovered that a malicious administrator can inject Groovy code that
can be executed remotely by a running Apache Syncope Core instance.


Users are recommended to upgrade to version 3.0.14 / 4.0.2, which
fix this issue by forcing the Groovy code to run in a sandbox.
