Synopsis

An application running on a remote web server host is affected by a vulnerability

Description

The version of Splunk installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the SVD-2025-1005 advisory.

 - In Splunk Enterprise versions below 10.0.1, 9.4.4, 9.3.6, and 9.2.8, and Splunk Cloud Platform versions below 9.3.2411.108, 9.3.2408.118 and 9.2.2406.123, a user who holds a role that contains the high- privilege capability `change_authentication`, could send multiple LDAP bind requests to a specific internal endpoint, resulting in high server CPU usage, which could potentially lead to a denial of service (DoS) until the Splunk Enterprise instance is restarted. See https://help.splunk.com/en/splunk- enterprise/administer/manage-users-and-security/10.0/manage-splunk-platform-users-and-roles/define-roles- on-the-splunk-platform-with-capabilities and https://help.splunk.com/en/splunk- enterprise/administer/manage-users-and-security/10.0/use-ldap-as-an-authentication-scheme/configure-ldap- with-splunk-web#cfe47e31_007f_460d_8b3d_8505ffc3f0dd__Configure_LDAP_with_Splunk_Web for more information.
