Ah, the HMI and other wonderful pieces of [REDACTED], er, software. Wesley McGrew is presenting today his talk which delves into a vulnerability with GE Fanuc’s iFIX product.
From McGrew Security Blog:
The specific examples discussed in these slides and my talk are problems with the architecture (and password storage!) of GE Fanuc’s iFIX. The above-described vulnerabilities were discovered on version 4.5, but are also present in the recently released 5.0 (older versions almost certainly have the same problem). They were reported to US-CERT (VU# 310355) and the vendor about six months ago, and this represents the first public disclosure of the problems, though they are basic/fundamental enough that any security geek would spot them pretty quickly upon taking a look at this product.
