OVERVIEW

This updated advisory is a follow-up to the original advisory titled ICSA-15-050-01 Siemens SIMATIC STEP 7 TIA Portal Vulnerabilities that was published February 19, 2015, on the NCCIC/ICS-CERT web site.

Siemens has identified two vulnerabilities in its SIMATIC STEP 7 (TIA Portal). Siemens has produced a patch that mitigates these vulnerabilities. These vulnerabilities were initially disclosed to Siemens by the Quarkslab team and Dmitry Sklyarov with PT-Security.

One of the vulnerabilities is remotely exploitable.

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. The other allows a user with local access the ability to reconstruct passwords.

Impact to individual organizations depends on many factors that are unique to each organization. NCCIC/ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their operational environment, architecture, and product implementation.

BACKGROUND

Siemens is a multinational company headquartered in Munich, Germany.

The affected product, SIMATIC Step 7 (TIA Portal), is engineering software for SIMATIC products. This software is deployed across several sectors including Chemical, Energy, Food and Agriculture, and Water and Wastewater Systems. Siemens estimates that these products are used primarily in the United States and Europe with a small percentage in Asia.

VULNERABILITY CHARACTERIZATION

VULNERABILITY OVERVIEW

Attackers with access to the network path between the client and the server could possibly intercept or modify Siemens industrial communications at Port 102/TCP and conduct a man-in-the-middle attack.

CVE-2015-1601b has been assigned to this vulnerability. A CVSS v2 base score of 5.8 has been assigned; the CVSS vector string is (AV:N/AC:M/Au:N/C:P/I:P/A:N).c

USE OF PASSWORD HASH WITH INSUFFICIENT COMPUTATIONAL EFFORTd

Attackers with read access to TIA project files could possibly reconstruct protection-level passwords or web server passwords.

CVE-2015-1602e has been assigned to this vulnerability. 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).f

VULNERABILITY DETAILS

EXPLOITABILITY

The Man-in-the-middle vulnerability can be exploited remotely, the password hash vulnerability requires local access.

EXISTENCE OF EXPLOIT

No known public exploits specifically target these vulnerabilities.

DIFFICULTY

Crafting a working exploit for these vulnerabilities would be moderately difficult. Crafting a successful man-in-the-middle attack would require access to the network between the client and the server. Local access would be required to access to the project files with additional work required to reconstruct passwords. These factors decrease the likelihood of a successful exploit.

MITIGATION

Siemens provides Update 1 for SIMATIC STEP 7 (TIA Portal) V13 SP1, which fixes the vulnerabilities. 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. 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.

As a general security measure Siemens also strongly recommends to protect network access with appropriate mechanisms. It is advised to configure the environment according to Siemens operational guidelines in order to run the devices in a protected IT environment. 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.

Minimize network exposure for all control system devices and/or systems, and ensure that they are not accessible from the Internet.
Locate control system networks and remote devices behind firewalls, and isolate them from the business network.
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. Also recognize that VPN is only as secure as the connected devices.

ICS-CERT also provides a section for control systems security recommended practices on the ICS-CERT web page at: http://ics-cert.us-cert.gov/content/recommended-practices. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. ICS-CERT reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.

Additional mitigation guidance and recommended practices are publicly available in the ICS‑CERT Technical Information Paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies, that is available for download from the ICS-CERT web site (http://ics-cert.us-cert.gov/).

Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to ICS-CERT for tracking and correlation against other incidents.

In addition, ICS-CERT recommends that users take the following measures to protect themselves from social engineering attacks:

Do not click web links or open unsolicited attachments in email messages.
Refer to Recognizing and Avoiding Email Scamsg for more information on avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacksh for more information on social engineering attacks.

How to Open Projects in TIA Portal V13 and Previous Versions ?

If you try to open a project you created in version 13 or earlier with version 14 or version 15, you will encounter an error.

By opening the TIA Portal and clicking browse, it will select the project you created earlier and give an error when opened.
If you have TIA Portal V14 or V15 installed on your computer, you cannot open the project created with V13. You can only open projects created with V13 SP1 or SP2.

Projects created in version 13 SP1 versions can be opened directly with version 13 SP1 / SP2.
