-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 # SSA-472630: Security Vulnerabilities Fixed in RUGGEDCOM CROSSBOW V5.4 Publication Date: 2023-08-08 Last Update: 2023-08-08 Current Version: 1.0 CVSS v3.1 Base Score: 9.8 SUMMARY ======= The RUGGEDCOM CROSSBOW server application before V5.4 contains multiple vulnerabilities that could allow an attacker to execute arbitrary database queries via SQL injection attacks, to create a denial of service condition, or to write arbitrary files to the application's file system. Siemens has released an update for RUGGEDCOM CROSSBOW and recommends to update to the latest version. AFFECTED PRODUCTS AND SOLUTION ============================== * RUGGEDCOM CROSSBOW - Affected versions: All versions < V5.4 - Remediation: Update to V5.4 or later version - Download: https://support.industry.siemens.com/cs/ww/en/view/109822716/ WORKAROUNDS AND MITIGATIONS =========================== Product-specific remediations or mitigations can be found in the section "Affected Products and Solution". 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. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity PRODUCT DESCRIPTION =================== RUGGEDCOM CROSSBOW is a secure access management solution designed to provide NERC CIP compliant access to Intelligent Electronic Devices. 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-2021-31239 An issue found in SQLite SQLite3 v.3.35.4 that could allow a remote attacker to cause a denial of service via the appendvfs.c function. CVSS v3.1 Base Score: 7.5 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:P/RL:O/RC:C CWE: CWE-125: Out-of-bounds Read * Vulnerability CVE-2022-37971 Microsoft Windows Defender Elevation of Privilege Vulnerability. An attacker who successfully exploited this vulnerability could gain specific limited SYSTEM privileges. This vulnerability could allow an attacker to delete data that could include data that results in the service being unavailable. CVSS v3.1 Base Score: 7.1 CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H/E:U/RL:O/RC:C CWE: CWE-269: Improper Privilege Management * Vulnerability CVE-2023-27411 The affected applications is vulnerable to SQL injection. This could allow an authenticated remote attackers to execute arbitrary SQL queries on the server database and escalate privileges. CVSS v3.1 Base Score: 8.8 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C CWE: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') * Vulnerability CVE-2023-37372 The affected applications is vulnerable to SQL injection. This could allow an unauthenticated remote attackers to execute arbitrary SQL queries on the server database. 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:P/RL:O/RC:C CWE: CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') * Vulnerability CVE-2023-37373 The affected applications accept unauthenticated file write messages. An unauthenticated remote attacker could write arbitrary files to the affected application's file system. CVSS v3.1 Base Score: 5.3 CVSS Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N/E:P/RL:O/RC:C CWE: CWE-306: Missing Authentication for Critical Function ACKNOWLEDGMENTS =============== Siemens thanks the following party for its efforts: * The UK's National Cyber Security Centre (NCSC) for reporting the vulnerabilities CVE-2023-27411, CVE-2023-37372, and CVE-2023-37373 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 (2023-08-08): 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").
