Siemens patches Heartbleed in popular SCADA system

Some of the company's other products are still vulnerable

Siemens released a security update to address the Heartbleed vulnerability in SIMATIC WinCC Open Architecture, a supervisory control and data acquisition (SCADA) system that's used in a large number of industries to operate processes, machines and production flows.

Heartbleed is a critical security flaw discovered earlier this month in OpenSSL, the most popular implementation of the TLS (Transport Layer Security) and SSL (Secure Sockets Layer) protocols.

The vulnerability can be exploited to extract passwords, encryption keys and other potentially sensitive information from the memory of TLS servers and clients that rely on OpenSSL for encrypted communications. While most of the discussion surrounding the vulnerability has focused on how it impacts Web servers, the flaw also affects desktop and mobile applications, embedded systems like routers, hardware appliances and industrial control systems, including those potentially used in critical infrastructure.

Siemens updated its Heartbleed security advisory Friday to announce the availability of WinCC OA version 3.12-P006 that fixes the flaw for WinCC OA 3.12, the only affected version of the product according to the company.

However, Heartbleed also affects other Siemens products: eLAN prior to version 8.3.3 when RIP is used, S7-1500 V1.5 when HTTPS is active, CP1543-1 V1.1 when FTPS is active and APE 2.0 when the SSL/TLS component is used in customer implementations.

ELAN customers can solve the security issue by updating to version 8.3.3, but the other affected products are yet to receive patches. In the meantime, Siemens suggests several mitigations in its security advisory that involve disabling or restricting access to the web server in S7-1500 and disabling or restricting access to FTPS in CP1543-1.

APE 2.0 customers can upgrade the OpenSSL installation in the product to version 1.0.1g by following instructions in a separate advisory published on the RuggedCom website. RuggedCom is a subsidiary of Siemens and the original maker of the product.

Educating from the epicentre - Why distributors are the pulse checkers of the channel

Educating from the epicentre - Why distributors are the pulse checkers of the channel

​As the channel changes and industry voices deepen, the need for clarity and insight heightens. Market misconceptions talk of an “under pressure” distribution space, with competitors in that fateful “race for relevance” across New Zealand. Amidst the cliched assumptions however, distribution is once again showing its strength, as a force to be listened to, rather than questioned. Traditionally, the role was born out of a need for vendors and resellers to find one another, acting as a bridge between the testing lab and the marketplace. Yet despite new technologies and business approaches shaking the channel to its very core, distributors remain tied to the epicentre - providing the voice of reason amidst a seismic industry shift. In looking across both sides of the vendor and partner fences, the middle concept of the three-tier chain remains centrally placed to understand the metrics of two differing worlds, as the continual pulse checkers of the local channel. This exclusive Reseller News Roundtable, in association with Dicker Data and rhipe, examined the pivotal role of distribution in understanding the health of the channel, educating from the epicentre as the market transforms at a rapid rate.
