AI-Generated

Splunk Enterprise for Windows versions prior to 10.4.2, 10.2.6, 10.0.9, 9.4.13, and 9.3.14 are vulnerable to a local privilege escalation issue that allows an attacker with access to the host to bind to the management port before the service initializes. This flaw enables the interception of authentication tokens from child processes, potentially compromising data integrity and confidentiality for the affected user account. Organizations using these versions should prioritize remediation to mitigate the risk of unauthorized access and data breaches.

Original NVD Description

In Splunk Enterprise for Windows versions below 10.4.2, 10.2.6, 10.0.9, 9.4.13, and 9.3.14, a local user with access to the Windows host could bind to the management port before Splunk Enterprise starts, intercept authentication tokens from child processes, and use those tokens to compromise all relevant data and system integrity available to the user account running Splunk Enterprise. The vulnerability is possible because the Windows management-port listener does not apply exclusive address binding protections before the service starts.
