SSA-711309: Denial of Service Vulnerability in the OPC UA Implementations of SIMATIC Products

Publication Date:	2023-09-12
Last Update:	2024-12-10
Current Version:	V2.2
CVSS v3.1 Base Score:	7.5

SUMMARY

The OPC UA implementations (ANSI C and C++) as used in several SIMATIC products contain a denial of service vulnerability that could allow an unauthenticated remote attacker to create a denial of service condition by sending a specially crafted certificate.

Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.

PRODUCT DESCRIPTION

SIMATIC BRAUMAT / SISTAR are industry-specific control systems especially for the control and monitoring of recipe-controlled production processes such as in the food, beverages and tobacco industries as well as for comparable batch-oriented production processes.

SIMATIC Cloud Connect 7 is an IoT Gateway to connect programmable logic controllers to cloud services and enables the connection of field devices with OPC UA server Interface as OPC UA clients.

SIMATIC Drive Controllers have been designed for the automation of production machines, combining the functionality of a SIMATIC S7-1500 CPU and a SINAMICS S120 drive control.

SIMATIC ET 200SP Open Controller is a PC-based version of the SIMATIC S7-1500 Controller including optional visualization in combination with central I/Os in a compact device.

SIMATIC IPC DiagMonitor monitors, reports, visualizes and logs the system states of the SIMATIC IPCs. It communicates with other systems and reacts when events occur.

SIMATIC NET PC software is a software product that is sold separately and implements the communications product from SIMATIC NET.

SIMATIC PCS 7 is a distributed control system (DCS) integrating SIMATIC WinCC, SIMATIC Batch, SIMATIC Route Control, OpenPCS 7 and other components.

SIMATIC PCS neo is a distributed control system (DCS).

SIMATIC S7-1500 CPU products have been designed for discrete and continuous control in industrial environments such as manufacturing, food and beverages, and chemical industries worldwide.

SIMATIC S7-1500 ODK CPUs provide functionality of standard S7-1500 CPUs but additionally provide the possibility to run C/C++ Code within the CPU-Runtime for execution of own functions / algorithms implemented in C/C++. They have been designed for discrete and continuous control in industrial environments such as manufacturing, food and beverages, and chemical industries worldwide.

SIMATIC S7-1500 Software Controller is a SIMATIC software controller for PC-based automation solutions.

SIMATIC S7-PLCSIM Advanced simulates S7-1200, S7-1500 and a few other PLC derivatives. Includes full network access to simulate the PLCs, even in virtualized environments.

SIMATIC WinCC is a supervisory control and data acquisition (SCADA) system.

SIMATIC WinCC Open Architecture (OA) is part of the SIMATIC HMI family. It is designed for use in applications requiring a high degree of customer-specific adaptability, large or complex applications and projects that impose specific system requirements or functions.

SIMATIC WinCC Runtime Professional is a visualization runtime platform used for operator control and monitoring of machines and plants.

SIMATIC WinCC Unified OPC UA Client enables WinCC Unified devices to connect with OPC UA servers.

SIMATIC WinCC Unified OPC UA Server allows clients to connect to WinCC Unified via the OPC UA standard.

Totally Integrated Automation Portal (TIA Portal) is a PC software that provides access to the complete range of Siemens digitalized automation services, from digital planning and integrated engineering to transparent operation.

VULNERABILITY DESCRIPTION

Un-/Collapse All

This chapter describes all vulnerabilities (CVE-IDs) addressed in this security advisory. Wherever applicable, it also documents the product-specific impact of the individual vulnerabilities.

Vulnerability CVE-2023-28831

The OPC UA implementations (ANSI C and C++) in affected products contain an integer overflow vulnerability that could cause the application to run into an infinite loop during certificate validation.

This could allow an unauthenticated remote attacker to create a denial of service condition by sending a specially crafted certificate.

CVSS v3.1 Base Score	7.5
CVSS v3.1 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-190: Integer Overflow or Wraparound
