How the mentioned CVE works:
This CVE exploits a feature in Apache Syncope designed for deployment customization, allowing administrators to provide custom Java or Groovy class implementations. A malicious administrator can abuse this functionality by injecting malicious Groovy code into the system. Because the machinery is configured for runtime reload, this injected code is not properly sandboxed in affected versions. Consequently, the malicious Groovy script is executed remotely by the Apache Syncope Core instance with the application’s privileges, leading to remote code execution on the underlying server. The vulnerability stems from the lack of a safe execution environment for the provided scripts.
Platform: Apache Syncope
Version: <3.0.14, 4.0.0-M0-4.0.2
Vulnerability : Code Injection
Severity: Critical
date: 2025-10-20
Prediction: 2025-11-03
What Undercode Say:
curl -s "https://syncope.apache.org/security" | grep -A 10 "CVE-2025"
// Malicious Groovy payload example println "hostname".execute().text
How Exploit:
Malicious admin logs into the Syncope admin console, navigates to the custom logic/implementation section, and inserts a malicious Groovy script. Upon triggering the associated workflow or logic, the script executes on the server.
Protection from this CVE:
Upgrade to Apache Syncope version 3.0.14 or 4.0.2. These patched versions enforce a Groovy sandbox, restricting the script’s access to dangerous operations and system resources.
Impact:
Remote Code Execution, Full System Compromise, Data Breach, Privilege Escalation.
