Description

In Splunk SOAR versions below 8.6.0, an authenticated user with no role assigned could submit a crafted file path to the Representational State Transfer (REST) API and execute arbitrary code. The vulnerability is possible because the REST API does not require an assigned role for the request and does not restrict the user-supplied file path to the intended temporary directory. For more information see Manage roles and permissions in Splunk SOAR (On-premises) (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/manage-your-splunk-soar-on-premises-users-and-accounts/manage-roles-and-permissions-in-splunk-soar-on-premises) and Splunk SOAR (On-premises) security information (https://help.splunk.com/en/splunk-soar/soar-on-premises/administer-soar-on-premises/8.5.0/introduction-to-splunk-soar-on-premises/splunk-soar-on-premises-security-information) in the Splunk documentation.

Executive Summary

This vulnerability in Splunk SOAR versions below 8.6.0 allows an authenticated user without any assigned role to submit a specially crafted file path to the REST API. This can lead to arbitrary code execution because the API does not enforce role requirements or restrict file paths to the intended temporary directory.

Impact Analysis

An attacker could exploit this to execute malicious code on the affected Splunk SOAR system, potentially leading to unauthorized access, data breaches, or system compromise. The impact depends on the user's privileges and the system's configuration.

Compliance Impact

This vulnerability could lead to unauthorized access or data breaches, which may violate compliance requirements under GDPR, HIPAA, or other regulations. It undermines data integrity and confidentiality, potentially resulting in legal penalties or reputational damage.

Mitigation Strategies

Upgrade Splunk SOAR to version 8.6.0 or later to address the vulnerability. Ensure all authenticated users have assigned roles with appropriate permissions. Review and restrict API access to prevent unauthorized file path submissions.
