Missing Authorization through the REST API in Splunk SOAR

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

In Splunk SOAR versions below 8.7.0, an authenticated user could change the Enterprise Security edition through the Representational State Transfer (REST) API and cause Splunk SOAR to apply the license change. The vulnerability is possible because Splunk SOAR authenticates requests to manage the Enterprise Security edition but does not authorize the caller before it applies the license change. For more information see Using the REST API reference for Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/rest-api-reference/8.7.0/using-the-splunk-soar-rest-api/using-the-rest-api-reference-for-splunk-soar-on-premises), Obtain and configure a Splunk SOAR (On-premises) license (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.7.0/configure-your-companys-settings-in-splunk-soar-on-premises/obtain-and-configure-a-splunk-soar-on-premises-license), and Integration of Splunk SOAR with Splunk Enterprise Security (https://help.splunk.com/en/splunk-enterprise-security-8/administer/8.7/automation-with-playbooks/integration-of-splunk-soar-with-splunk-enterprise-security) in the Splunk documentation.
