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.
AnalysisAI
Code execution via Groovy sandbox bypass in Apache Syncope 3.0 through 3.0.16, 4.0 through 4.0.5, and 4.1.0 allows a high-privileged administrator holding Implementations entitlements to run untrusted code outside the sandbox. By placing payload logic in a Groovy class static initializer, the attacker reaches a non-sandboxed execution path, yielding full confidentiality, integrity, and availability impact. …

RemediationAI
Within 24 hours: Inventory all administrator accounts with Implementations entitlements and audit access logs for the past 60 days; identify and isolate any suspicious activity. Within 7 days: Revoke Implementations entitlements from all but critical administrators; enforce privileged access management (PAM) controls, mandatory MFA, and real-time alerting on Groovy-related API calls for retained accounts. …
