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-2023-0803 advisory.

 - In Splunk Enterprise versions lower than 8.2.12, 9.0.6, and 9.1.1, an attacker can use the `printf` SPL function to perform a denial of service (DoS) against the Splunk Enterprise instance. (CVE-2023-40594)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade Splunk Enterprise to versions 8.2.12, 9.0.6, or 9.1.1.
Splunk is actively monitoring and patching Splunk Cloud Platform instances.
