Description
In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, a user who does not hold the "admin" or "power" Splunk roles could bypass Search Processing Language (SPL) safeguards for risky commands through the Job Details dashboard. The injected SPL could run using the permissions of an authenticated user who opens a crafted Job Details dashboard link. This could allow access to all relevant data and affect system integrity within those permissions. The vulnerability is possible because the Job Details dashboard does not correctly neutralize a caller-supplied search identifier before placing it into SPL searches. The vulnerability requires the attacker to phish the user by tricking them into opening the crafted link. The user who does not hold the "admin" or "power" Splunk roles should not be able to exploit the vulnerability at will.

AI Analysis

Impact

The vulnerability allows a user lacking admin or power privileges to bypass Search Processing Language safeguards by injecting arbitrary SPL through a crafted Job Details dashboard link. The system fails to neutralize the caller‑supplied job identifier, enabling the injected SPL to run with the authenticated user’s credentials. This can expose all data the user is allowed to read and alter job state, thereby compromising the integrity of the system within that user’s authorization scope. The weakness is an input validation flaw, identified as CWE‑20.

Affected Systems

Affected product is Splunk Enterprise. Versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14 are vulnerable. Users running these releases should inspect whether Splunk Web is enabled, as the issue is triggered via the Job Details dashboard.

Risk and Exploitability

The CVSS score of 6.4 indicates a medium severity. Because an EPSS score is not available, the likelihood of exploitation is unknown from the advisory. The vulnerability is not listed in the CISA KEV catalog, yet it remains exploitable if a user can be tricked into opening a crafted link while Splunk Web is active. Official remediation requires upgrading to the patched releases; alternatively, disabling Splunk Web provides a workaround for environments that cannot upgrade immediately.

Remediation

Vendor Solution

Upgrade Splunk Enterprise to versions 10.4.2, 10.2.6, 10.0.9, and 9.4.14, or higher.

Vendor Workaround

The vulnerability affects instances with Splunk Web turned on. Turning Splunk Web off is a possible workaround. See [Disable unnecessary Splunk Enterprise components](https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.4/install-splunk-enterprise-securely/disable-unnecessary-splunk-enterprise-components) and the [web.conf](https://help.splunk.com/en/splunk-enterprise/administer/admin-manual/10.4/configuration-file-reference/10.4.0-configuration-file-reference/web.conf) configuration specification file for more information on turning off Splunk Web.

OpenCVE Recommended Actions

  • Upgrade Splunk Enterprise to version 10.4.2 or later, 10.2.6 or later, 10.0.9 or later, or 9.4.14 or later.
  • If an upgrade is not immediately possible, disable Splunk Web by updating web.conf or following Splunk’s documentation on turning off unnecessary components.
  • Restrict non‑admin users from accessing the Job Details dashboard and enforce least‑privilege role policies to limit the exposure of job identifiers.
