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-2022-1103 advisory.

- In Splunk Enterprise versions below 8.2.9 and 8.1.12, the way that the rex' search command handles field names lets an attacker bypass SPL safeguards for risky commands. The vulnerability requires the attacker to phish the victim by tricking them into initiating a request within their browser. The attacker cannot exploit the vulnerability at will. (CVE-2022-43563)

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 9.0.2203, 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.
