-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 # SSA-984700: Password Storage Vulnerability in SIMATIC IT UADM Publication Date: 2019-10-08 Last Update: 2019-10-08 Current Version: 1.0 CVSS v3.0 Base Score: 6.8 SUMMARY ======= A vulnerability has been identified in the SIMATIC IT Unified Architecture Discrete Manufacturing product that caused a password to be encrypted with a predicable encryption key. An authenticated attacker could potentially recover the password and gain access to the TeamCenter station connected to the instance. Siemens provides updates to address the vulnerability, and recommends specific mitigations. AFFECTED PRODUCTS AND SOLUTION ============================== * SIMATIC IT UADM - Affected versions: All versions < V1.3 - Remediation: Update to V1.3 - Download: SIMATIC IT UADM software can be obtained from your local Siemens account manager. WORKAROUNDS AND MITIGATIONS =========================== Siemens has identified the following specific workarounds and mitigations that customers can apply to reduce the risk: * Protect network access to port 1434/tcp of machines running SIMATIC IT UADM software. * Apply cell protection concept and implement Defense-in-Depth. 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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity PRODUCT DESCRIPTION =================== SIMATIC IT Unified Architecture Discrete Manufacturing (SIMATIC IT UADM) is a software product specifically designed and developed by Siemens by leveraging the SIMATIC IT Unified Architecture foundation. SIMATIC IT UADM is the specialized product addressing the needs of the discrete industry market. It is designed to satisfy the most common needs of industries in which specific macro areas are dedicated to executing sequential discrete manufacturing functions in order to produce the desired product. VULNERABILITY CLASSIFICATION ============================ The vulnerability classification has been performed by using the CVSS scoring system in version 3.0 (CVSS v3.0) (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. * Vulnerability CVE-2019-13929 An authenticated remote attacker with network access to port 1434/tcp of SIMATIC IT UADM could potentially recover a password that can be used to gain read and write access to the related TeamCenter station. The security vulnerability could be exploited only if the attacker is authenticated. No user interaction is required to exploit this security vulnerability. Successful exploitation of the security vulnerability compromises the confidentiality of the targeted system. At the time of advisory publication no public exploitation of this security vulnerability was known. CVSS v3.0 Base Score: 6.8 CVSS v3.0 Vector: CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:N/A:N/E:P/RL:O/RC:C ADDITIONAL INFORMATION ====================== For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories HISTORY DATA ============ V1.0 (2019-10-08): Publication Date TERMS OF USE ============ Siemens Security Advisories are subject to the terms and conditions contained in Siemens' underlying license terms or other applicable agreements previously agreed to with Siemens (hereinafter "License Terms").
