Splunk UFW Windows <9.4.2 perms flaw
CVE-2025-20298 Published on June 2, 2025
Incorrect permission assignment on Universal Forwarder for Windows during new installation or upgrade
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.
Weakness Type
Incorrect Permission Assignment for Critical Resource
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. When a resource is given a permissions setting that provides access to a wider range of actors than required, it could lead to the exposure of sensitive information, or the modification of that resource by unintended parties. This is especially dangerous when the resource is related to program configuration, execution or sensitive user data.
