Unauthenticated Network Traffic Access in Splunk SOAR

Publication date: 2026-08-19

Last updated on: 2026-08-19

Assigner: Cisco Systems, Inc.

Description

In Splunk SOAR versions below 8.6.0, an unauthenticated user who can observe or alter network traffic between Splunk SOAR and a configured CyberArk Representational State Transfer (REST) server could access or modify all relevant data exchanged through that credential manager. The vulnerability is possible because the CyberArk REST client does not verify server certificates by default. The attack requires the attacker to have network-path interception capability between Splunk SOAR and the configured CyberArk REST server.

Attack-Flow Graph

Executive Summary

This vulnerability affects Splunk SOAR versions below 8.6.0. It allows an unauthenticated user with network interception capability to access or modify data exchanged between Splunk SOAR and a CyberArk REST server. The issue occurs because the CyberArk REST client does not verify server certificates by default.

Detection Guidance

Detecting this vulnerability requires checking if Splunk SOAR versions below 8.6.0 are using CyberArk REST server connections without certificate verification. Inspect Splunk SOAR configuration files for CyberArk REST server settings and verify if server certificate validation is enabled. Monitor network traffic between Splunk SOAR and CyberArk REST servers for unencrypted or improperly secured connections.

Impact Analysis

An attacker could intercept sensitive data or alter communications between Splunk SOAR and the CyberArk REST server. This could lead to unauthorized access to credentials or other confidential information.

Compliance Impact

This vulnerability could lead to unauthorized access or modification of sensitive data, potentially violating compliance requirements such as GDPR or HIPAA. Unauthorized access to credentials or data may result in data breaches.

Mitigation Strategies

Upgrade Splunk SOAR to version 8.6.0 or higher to ensure default certificate verification is enabled. If upgrading is not immediately possible, manually configure Splunk SOAR to validate CyberArk REST server certificates. Restrict network access between Splunk SOAR and CyberArk REST servers to trusted paths only.
