ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at. Also recognize that VPN is only as secure as the connected devices.

When remote access is required, use secure methods, such as Virtual Private Networks (VPNs), recognizing that VPNs may have vulnerabilities and should be updated to the most current version available.

Locate control system networks and remote devices behind firewalls, and isolate them from the business network.

Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.

An overview of the operational guidelines for Industrial Security (with the cell protection concept) is available at: For more information on these vulnerabilities and detailed instructions, please see Siemens Security Advisory SSA-315836 at the following location: ICS-CERT encourages asset owners to take additional defensive measures to protect against this and other cybersecurity risks. It is advised to configure the environment according to Siemens operational guidelines in order to run the devices in a protected IT environment. As a general security measure Siemens also strongly recommends to protect network access with appropriate mechanisms.

Update 5 can be obtained here: - End Update A Part 2 of 2 - After applying the update, Siemens strongly recommends to change protection-level and web server passwords. The update can be obtained here: - Begin Update A Part 2 of 2 - Siemens also provides Update 5 for SIMATIC STEP 7 (TIA Portal) V12 SP1 to fix the vulnerabilities. MITIGATION Siemens provides Update 1 for SIMATIC STEP 7 (TIA Portal) V13 SP1, which fixes the vulnerabilities. These factors decrease the likelihood of a successful exploit. Local access would be required to access to the project files with additional work required to reconstruct passwords. DIFFICULTY Crafting a working exploit for these vulnerabilities would be moderately difficult.Ĭrafting a successful man-in-the-middle attack would require access to the network between the client and the server. EXISTENCE OF EXPLOIT No known public exploits specifically target these vulnerabilities.

VULNERABILITY DETAILS EXPLOITABILITY The Man-in-the-middle vulnerability can be exploited remotely, the password hash vulnerability requires local access. A CVSS v2 base score of 1.9 has been assigned the CVSS vector string is (AV:L/AC:M/Au:N/C:P/I:N/A:N). CVE-2015-1602 has been assigned to this vulnerability. USE OF PASSWORD HASH WITH INSUFFICIENT COMPUTATIONAL EFFORT Attackers with read access to TIA project files could possibly reconstruct protection-level passwords or web server passwords.

VULNERABILITY CHARACTERIZATION VULNERABILITY OVERVIEW. Siemens estimates that these products are used primarily in the United States and Europe with a small percentage in Asia.

This software is deployed across several sectors including Chemical, Energy, Food and Agriculture, and Water and Wastewater Systems. Win10-Support for TIA Portal V14 SP1 incl. Freely editable comments for array and UDT New functions for the operability TIA updater: Fast mass update.

The affected product, SIMATIC Step 7 (TIA Portal), is engineering software for SIMATIC products. BACKGROUND Siemens is a multinational company headquartered in Munich, Germany. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation. Impact to individual organizations depends on many factors that are unique to each organization. The other allows a user with local access the ability to reconstruct passwords. AFFECTED PRODUCTS - Begin Update A Part 1 of 2 - Siemens reports that the vulnerabilities affect the following versions of SIMATIC STEP 7 (TIA Portal): SIMATIC STEP 7 (TIA Portal) V13: All versions prior to V13 SP1 Upd1 SIMATIC STEP 7 (TIA Portal) V12: All versions prior to V12 SP1 Upd5 - End Update A Part 1 of 2 - IMPACT One vulnerability could allow for a successful man-in-the-middle attack, allowing the attacker to view and modify data sent between the user and the system.

One of the vulnerabilities is remotely exploitable. These vulnerabilities were initially disclosed to Siemens by the Quarkslab team and Dmitry Sklyarov with PT-Security.
