SQL Injection in Splunk Enterprise via Data Orchestration

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 execute attacker-chosen Structured Query Language (SQL) queries through the Data Orchestration jobs endpoint, allowing for access to substantially all data stored by Data Orchestration, including jobs owned by other users and stored connection credentials. The vulnerability is possible because Data Orchestration builds a database query from user-controlled job filter values without using parameterized queries. For more information see About configuring role-based user access (https://help.splunk.com/en/splunk-enterprise/administer/manage-users-and-security/10.2/manage-splunk-platform-users-and-roles/about-configuring-role-based-user-access) in the Splunk documentation.

Exploitability

CWE
CWE Icon
KEV
KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This vulnerability affects Splunk Enterprise versions below 10.4.2, 10.2.6, 10.0.9, and 9.4.14. A non-admin or non-power user can execute attacker-controlled SQL queries via the Data Orchestration jobs endpoint. The issue arises because user-provided job filter values are directly used to build database queries without parameterization, enabling access to nearly all Data Orchestration data, including other users' jobs and stored credentials.

Impact Analysis

An attacker with low-privilege access could extract sensitive data such as stored connection credentials or job details from other users. This could lead to unauthorized data access, potential credential misuse, or further exploitation within the Splunk environment.

Compliance Impact

This vulnerability could violate compliance requirements by enabling unauthorized data access. GDPR may be breached if personal data is exposed, while HIPAA could be violated if protected health information is compromised. Organizations must address this to maintain regulatory compliance.

Mitigation Strategies

Upgrade Splunk Enterprise to versions 10.4.2, 10.2.6, 10.0.9, or 9.4.14 or later to address the vulnerability.
