CVE-2025-22621 in App for SOAR
Summary
by MITRE • 01/07/2025
In versions 1.0.67 and lower of the Splunk App for SOAR, the Splunk documentation for that app recommended adding the `admin_all_objects` capability to the `splunk_app_soar` role. This addition could lead to improper access control for a low-privileged user that does not hold the “admin“ Splunk roles.

The vulnerability identified as CVE-2025-22621 resides within the Splunk App for SOAR version 1.0.67 and earlier releases, representing a critical access control flaw that undermines the principle of least privilege in security implementations. This issue stems from the documentation recommendations provided by Splunk itself, which inadvertently advised administrators to grant the admin_all_objects capability to the splunk_app_soar role. The technical flaw manifests when a low-privileged user who does not possess the standard admin Splunk roles gains access to functionality that should remain restricted to high-privilege accounts, creating an unintended escalation path that violates fundamental security boundaries.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it enables unauthorized users to potentially access sensitive data and perform administrative actions within the SOAR environment. When the admin_all_objects capability is improperly assigned to the splunk_app_soar role, it effectively grants users with that role the ability to access all objects within the Splunk environment, regardless of their intended scope or permissions. This situation creates a dangerous precedent where users who should only have limited access can potentially view, modify, or delete critical security artifacts, incident responses, and automated workflows that are typically protected from lower-privileged accounts.
From a cybersecurity perspective, this vulnerability aligns with CWE-284, which addresses improper access control, and represents a classic case of privilege creep where administrative capabilities are unintentionally extended beyond their intended scope. The flaw also maps to several ATT&CK techniques including T1078 for valid accounts and T1566 for social engineering, as it could enable attackers to exploit the misconfigured permissions for lateral movement and persistence within the security operations environment. The vulnerability essentially creates a backdoor through which malicious actors could gain elevated privileges without detection, as the misconfiguration would not trigger standard security monitoring alerts that would normally flag explicit privilege escalation attempts.
Organizations utilizing the Splunk App for SOAR must immediately remediate this vulnerability by reviewing and removing the admin_all_objects capability from the splunk_app_soar role configuration. The recommended mitigation strategy involves conducting a comprehensive audit of all role assignments and capabilities within the Splunk environment, ensuring that no low-privileged roles inadvertently inherit administrative permissions. Security teams should implement regular configuration reviews and establish automated monitoring to detect unauthorized changes to role permissions, particularly focusing on the splunk_app_soar role and similar application-specific roles. Additionally, organizations should consider implementing role-based access control policies that enforce strict separation of duties and ensure that security documentation accurately reflects the minimum required permissions for each role rather than recommending overly permissive configurations that could introduce security risks.
