XXE in Splunk Dashboard Tab Label Field

IdentifiersCVE-2025-20369CWE-611· Improper Restriction of XML…

CVE-2025-20369 is an XML External Entity (XXE) injection vulnerability affecting Splunk Enterprise versions prior to 9.4.4, 9.3.6, and 9.2.8, and Splunk Cloud Platform versions prior to 9.3.2411.108, 9.3.2408.118, and 9.2.2406.123. According to the provided description, a low-privilege authenticated user who does not have the "admin" or "power" Splunk roles can inject XXE payloads through the dashboard tab label field. Successful exploitation can trigger XML parser processing of external entities, leading to denial-of-service conditions.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

The stated impact is denial of service. A low-privilege user can abuse the vulnerable XML processing path via the dashboard tab label field to cause service disruption or resource exhaustion conditions in the affected Splunk deployment. No evidence was provided in the supplied content for impacts beyond DoS.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, limit dashboard creation and editing capabilities to trusted users only, especially access to fields such as dashboard tab labels that may be parsed as XML. Monitor for anomalous dashboard modifications and potential XML parser abuse. However, the provided content does not specify an official vendor mitigation beyond upgrading.

Remediation

Patch, then assume compromise.

Upgrade Splunk Enterprise to version 9.4.4, 9.3.6, 9.2.8, or later. Upgrade Splunk Cloud Platform to version 9.3.2411.108, 9.3.2408.118, 9.2.2406.123, or later. Applying a vendor-fixed release is the primary remediation identified in the provided content.
