EUVD-2023-60691
Yonyou U8 Cloud contains an unauthenticated Java deserialization vulnerability in the nc.impl.pub.filesystem.FileManageServlet component that allows remote unauthenticated attackers to execute arbitrary OS commands by sending a serialized payload via POST request.

Exploitation evidence was first observed by the Shadowserver Foundation on 2025-02-13.
