Advisory ID: SVD-2022-1101 CVE ID: CVE-2022-43561
Published: 2022-11-02 Last Update: 2022-11-02
CVSSv3.1 Score: 6.4, M6.4, CVSSv3.1 Vector: CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U
Medium /C:H/I:H/A:H
CWE: CWE-79 Bug ID: SPL-207040
Description
In Splunk Enterprise versions below 8.1.12, 8.2.9, and 9.0.2, a remote user
that holds the "power" Splunk role can store arbitrary scripts that can lead
to persistent cross-site scripting (XSS). The vulnerability affects instances
with Splunk Web enabled.
Solution
For Splunk Enterprise, upgrade versions to 8.1.12, 8.2.9, 9.0.2, or higher.
For Splunk Cloud Platform versions below 9.0.2208, 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 .
Product Status
Product Version Component Affected Version Fixed Version
Splunk Enterprise 8.1 Splunk Web 8.1.11 and lower 8.1.12
Splunk Enterprise 8.2 Splunk Web 8.2.0 to 8.2.8 8.2.9
Splunk Enterprise 9.0 Splunk Web 9.0.0 to 9.0.1 9.0.2
Splunk Cloud Platform Splunk Web 9.0.2205 and lower 9.0.2208
Mitigations and Workarounds
If users do not log in to Splunk Web on indexers in a distributed environment,
disable Splunk Web on those indexers. See Disable unnecessary Splunk
Enterprise components and the web.conf configuration specification file for
more information on disabling Splunk Web.
Detections
Splunk XSS in "Save Table" dialog header in search/table page
This is a detection search to find persistent XSS that was included while
inputting data in the 'Save Table' dialog in the affected versions of Splunk
Enterprise.
Severity
Splunk rated the vulnerability as Medium. The vulnerability lets a remote
authenticated user with the power role to store arbitrary scripts, but
exploitation requires a multistep process by the victim. Hence, Splunk scored
the vulnerability as 6.4 with a CVSSv3.1 vector of CVSS:3.1/AV:N/AC:H/PR:H/
UI:R/S:U/C:H/I:H/A:H.
If the Splunk Enterprise instance does not run Splunk Web, there is no impact
and the severity is Informational.
