DescriptionCVE.org

In FireAMP versions below 2.1.15, a user who holds a role that can edit, create, or run playbooks in Splunk SOAR could run the add listitem action in a Safe Mode playbook while that action is listed as read-only, which could allow for unauthorized changes to file lists. The vulnerability is possible because the FireAMP connector action manifest classifies the add listitem action as read-only even though the action updates file lists. For more information see Manage settings for a playbook in Splunk SOAR (https://help.splunk.com/en/splunk-soar/soar-cloud/build-playbooks/manage-playbooks-and-playbook-settings/manage-settings-for-a-playbook-in-splunk-soar-cloud) in the Splunk documentation.

AnalysisAI

FireAMP connector versions below 2.1.15 for Splunk SOAR allow authenticated playbook editors to bypass Safe Mode restrictions by invoking the add listitem action, which the connector manifest incorrectly classifies as read-only despite it performing write operations on file lists. Exploitation requires a high-privilege role (playbook edit/create/run), limiting the attack surface to trusted internal SOAR users. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated user who has been granted one of three specific Splunk SOAR roles: the ability to edit, create, or run playbooks. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:L/A:N) scores 2.7, placing this firmly in the Low severity tier. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A Splunk SOAR operator who holds a playbook editor role creates or modifies a Safe Mode playbook to include the FireAMP add listitem action. Because the connector manifest incorrectly labels this action as read-only, Safe Mode does not block its execution, and the operator successfully adds or modifies entries in protected file lists beyond what their authorization should permit. …
Remediation Upgrade FireAMP to version 2.1.15 or later, which corrects the action manifest classification so that add listitem is properly treated as a write operation and blocked under Safe Mode playbooks. … Detailed patch versions, workarounds, and compensating controls in full report.
