medium Nessus Plugin ID 166933

Language:

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-2022-1112 advisory.

- In Splunk Enterprise versions below 8.2.9, 8.1.12, and 9.0.2, sending a malformed file through the Splunk- to-Splunk (S2S) or HTTP Event Collector (HEC) protocols to an indexer results in a blockage or denial-of- service preventing further indexing. (CVE-2022-43572)

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

Solution

For Splunk Enterprise, upgrade versions to 8.1.12, 8.2.9, 9.0.2, or higher. For Splunk Cloud Platform versions below 9.0.2211, Splunk is actively patching and monitoring the Splunk Cloud instances. To request an immediate upgrade, determine which version of Splunk Cloud Platform you're running, then create a new support case.
