Estado: AnalizadaAlta (8)—

In Universal Forwarder for Windows versions below 9.4.2, 9.3.4, 9.2.6, and 9.1.9, a new installation of or an upgrade to an affected version can result in incorrect permissions assignment in the Universal Forwarder for Windows Installation directory (by default, C:\Program Files\SplunkUniversalForwarder). This lets non-administrator users on the machine access the directory and all its contents.
