# SSA-555707: Information Disclosure Vulnerability in Simcenter STAR-CCM+

Publication Date:        2022-08-09
Last Update:             2022-08-09
Current Version:         1.0
CVSS v3.1 Base Score:    5.3


SUMMARY
=======

Simcenter STAR-CCM+ contains an information disclosure vulnerability
when using the Power-on-Demand public license server. An attacker
could access a system's host, user, and display name.    Siemens is
preparing updates and recommends specific countermeasures for products
where updates are not, or not yet available.


AFFECTED PRODUCTS AND SOLUTION
==============================


* Simcenter STAR-CCM+ 
  - Affected versions:
       All versions only if the Power-on-Demand public license server is used
  - Remediation:
       Currently no fix is available

       See recommendations from section "Workarounds and Mitigations"


WORKAROUNDS AND MITIGATIONS
===========================

Siemens has identified the following specific workarounds and mitigations that
customers can apply to reduce the risk:

  * Set the environmental variable STARLICENSEHIDE to 1. This will send the string
    "unknown" for the user, host and display name instead of the real values.
    The setting is  supported since version V8.04 (June 2013) of Simcenter STAR-
    CCM+
  * Avoid using sensitive or personal data in user, host and display names




Please follow the "General Security Recommendations".


GENERAL SECURITY RECOMMENDATIONS
================================

As a general security measure, Siemens strongly recommends to protect
network access to devices with appropriate mechanisms. In order to
operate the devices in a protected IT environment, Siemens recommends
to configure the environment according to Siemens' operational
guidelines for Industrial Security (Download:
https://www.siemens.com/cert/operational-guidelines-industrial-
security), and to follow the recommendations in the product manuals.

PRODUCT DESCRIPTION
===================

Simcenter STAR-CCM+ is a multiphysics computational fluid dynamics
(CFD) software for the simulation of products operating under
real-world conditions.

VULNERABILITY CLASSIFICATION
============================

The vulnerability classification has been performed by using the CVSS scoring
system in version 3.1 (CVSS v3.1) (https://www.first.org/cvss/). The CVSS
environmental score is specific to the customer's environment and will impact
the overall CVSS score. The environmental score should therefore be
individually defined by the customer to accomplish final scoring.

An additional classification has been performed using the CWE classification, a
community-developed list of common software security weaknesses. This serves as
a common language and as a baseline for weakness identification, mitigation,
and prevention efforts. A detailed list of CWE classes can be found at:
https://cwe.mitre.org/.



* Vulnerability CVE-2022-34659

  Affected applications expose user, host and display name of users,
  when the public license server is used. This could allow an attacker
  to retrieve this information.

    CVSS v3.1 Base Score: 5.3
    CVSS Vector:          CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:P/RL:T/RC:C
    CWE:                  CWE-200: Exposure of Sensitive Information to an Unauthorized
                          Actor
