In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway versions below 3.10.10, 3.9.24, and 3.8.71, a user who holds a Splunk role with permissions to list storage passwords but does not hold Splunk Secure Gateway administration privileges could access Mobile Device Management signing secrets that compromise all affected mobile-device enrollment trust through Splunk Secure Gateway. The vulnerability is possible because Splunk Secure Gateway Representational State Transfer (REST) API endpoints for deployment bundle, Security Assertion Markup Language setup, and companion app workflows do not require Splunk Secure Gateway administration privileges before processing requests.
AnalysisAI
Unauthorized access to Mobile Device Management signing secrets in Splunk Secure Gateway allows a low-privileged Splunk user to compromise all mobile-device enrollment trust. Affected are Splunk Enterprise below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, and Splunk Secure Gateway below 3.10.10, 3.9.24, and 3.8.71. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated Splunk account holding a role with the 'list storage passwords' permission - this is not a default end-user capability and typically indicates elevated, though not administrative, access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) reflects a network-reachable, low-complexity flaw requiring only low-level authentication - consistent with the real-world exploitation path of an insider or compromised low-privilege account invoking unauthenticated-to-SGW REST endpoints over the network. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with a Splunk account granted the 'list storage passwords' capability - obtained through a compromised employee account or via insider access - sends a crafted HTTP request to one of the unprotected Splunk Secure Gateway REST API endpoints (such as the deployment bundle or SAML setup endpoint) over the network. Without requiring Secure Gateway administration privileges, the endpoint processes the request and returns MDM signing secrets. … |
| Remediation | Upgrade Splunk Enterprise to version 10.4.2, 10.2.6, 10.0.9, or 9.4.14 (or later within each branch), and Splunk Secure Gateway to version 3.10.10, 3.9.24, or 3.8.71 (or later within each branch), per Splunk advisory SVD-2026-0801 at https://advisory.splunk.com/advisories/SVD-2026-0801. … Detailed patch versions, workarounds, and compensating controls in full report. |
