GENERAL SECURITY RECOMMENDATIONS ================================ As a general security measure Siemens strongly recommends to protect network access to affected products with appropriate mechanisms. It is advised to follow recommended security practices in order to run the devices in a protected IT environment. PRODUCT DESCRIPTION =================== Desigo CC is the integrated building management platform for managing high-performing buildings. With its open design, it has been developed to create comfortable, safe and efficient facilities. It is easily scalable from simple single-discipline systems to fully integrated buildings. Desigo CC Compact extends the portfolio with a tailored solution for small and medium-sized buildings. Advanced Reporting for Desigo CC and Desigo CC Compact is an optional extension module that allows customers to create sophisticated reports with many widgets (e.g. bar-charts, ...) to monitor and compare over time selected KPIs. 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-2020-10055 Affected applications are delivered with a 3rd party component (BIRT) that contains a remote code execution vulnerability if the Advanced Reporting Engine is enabled. The vulnerability could allow a remote unauthenticated attacker to execute arbitrary commands on the server with SYSTEM privileges. CVSS v3.1 Base Score: 9.8 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C CWE: CWE-94: Improper Control of Generation of Code ('Code Injection') 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 (2020-08-11): 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").
