Severity: moderate Affected versions:
- Apache Syncope (org.apache.syncope.core:syncope-core-spring) 3.0 through 3.0.16 - Apache Syncope (org.apache.syncope.core:syncope-core-spring) 4.0 through 4.0.5 - Apache Syncope (org.apache.syncope.core:syncope-core-spring) 4.1 through 4.1.0 Description: Improper Isolation or Compartmentalization vulnerability in Apache Syncope. An administrator with adequate entitlements for Implementations can create a malicious Groovy class containing untrusted code reaching a non-sandboxed execution path via the class static initializer. This issue affects Apache Syncope: 3.0 through 3.0.16, 4.0 through 4.0.5, 4.1.0. Users are recommended to upgrade to version 4.0.6 / 4.1.1, which fix this issue by forcing even the static initializer in Groovy code to run in a sandbox.
