Received Received - Intake

Authenticated Command Injection in Splunk Enterprise

Publication date: 2026-08-19

Last updated on: 2026-08-19

Assigner: Cisco Systems, Inc.

Description

In Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14, an authenticated user who does not hold a role with the edit_manager_xml capability could write a malicious Splunk Web Manager Extensible Markup Language (XML) configuration. When the same user opens the affected Splunk Web Manager page, Splunk Enterprise runs attacker-controlled operating-system commands as the user account running Splunk Enterprise. The vulnerability is possible because Splunk Web does not require the edit_manager_xml capability before accepting Splunk Web Manager XML configuration changes.

Attack-Flow Graph

Executive Summary

This vulnerability affects Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14. An authenticated user without the edit_manager_xml capability can write a malicious XML configuration for Splunk Web Manager. When the user opens the affected page, Splunk runs attacker-controlled OS commands as the Splunk user account.

Impact Analysis

An attacker could execute arbitrary commands on the system running Splunk Enterprise with the privileges of the Splunk user. This could lead to data theft, system compromise, or further network infiltration depending on the attacker's goals.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, violating GDPR and HIPAA requirements for data protection and access controls. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Upgrade Splunk Enterprise to a patched version (10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later) immediately to address the vulnerability. Ensure only users with the edit_manager_xml capability can modify Splunk Web Manager XML configurations.
