AI description
CVE-2025-20386 affects Splunk Enterprise for Windows versions below 10.0.2, 9.4.6, 9.3.8, and 9.2.10. A new installation or an upgrade to an affected version can result in incorrect permissions assignment in the Splunk Enterprise for Windows Installation directory. This vulnerability allows non-administrator users on the machine to access the directory and all its contents. The incorrect permissions assignment during installation or upgrades grants unprivileged local users read and write access to sensitive configuration files. An attacker with local access could exploit these permissions to modify system configuration or inject malicious code.
