TB094 Arbitrary Code Execution May Be Performed by Engine System Administrators

Impact

FIPS 199 Severity Level: High

CVSS Score: 8.7 based on:

Attack Vector (AV): N

Attack Complexity (AC): L

Privileges Required (PR): H

User Interaction (UI): N

Scope (S): C

Confidentiality (C): H

Integrity (I): H

Availability (A): H 

Under certain conditions, arbitrary code execution may be performed by sysadmins. Exploitation requires sysadmin privileges. This security bug was discovered internally by Delphix Engineering.

The local engine configuration can be modified by a sysadmin privileged user to improperly enable the download and execution of arbitrary code by manipulating internal configuration values.

Contributing Factors

This article applies to the following versions of the Delphix engine:

Major Release	All Sub Releases
6.0	6.0.8.0, 6.0.8.1, 6.0.9.0, 6.0.10.0, 6.0.10.1

This is applicable to both the Virtualization Engine and Masking Engine.

Symptoms

Arbitrary code execution.

Relief/Workaround

Delphix highly recommends upgrading to 6.0.11.0 if the engine is on any of the affected releases.

Mitigations

1. Ensure the Delphix Engine is deployed on a controlled access network and only appropriately privileged personnel have access to the network and Delphix Engine management interfaces.

2. Use LDAP authenticated named users to facilitate separation of duties, least privileges, and auditing. Disable the out-of-the-box generic SYSADMIN account as described in the User Management section of the Engine documentation.

3. If the builtin SYSADMIN account remains enabled ensure that the credential is managed under a Privileged Access Management procedure.
