+ - Many Stuxnet Bugs Still Unpatched by Siemens->

Trailrunner7 (1100399) writes "The media storm over the Stuxnet worm may have passed, but many of the software holes that were used by the worm remain unpatched and leave Siemens customers open to a wide range of potentially damaging cyber attacks, according to industrial control system expert Ralph Langner.
Langner said that the media paid too much attention to the four, zero day Windows vulnerabilities that enabled the Stuxnet worm, but overlooked the other security holes used by the worm. Unlike the Windows vulnerabilities, which Microsoft quickly fixed, many of the holes in Siemens' products remain unpatched, he contends.

Langner enumerates three types of exploits used by Stuxnet — only one category of which (Windows operating system exploits) have been closed. The other two are Windows applications exploits aimed at Siemens Siemens Simatic Manager and the Siemens WinCC SCADA application, and controller exploits aimed at Siemens S70-300 and 400 series controllers."
