Updated: SANS Storm Center has more info on the CitechSCADA vulnerbaility here.
The AP reports, via the Star Tribune, that Core Security Technologies has identified a significant hole in CitechSCADA software. I'm sure this will be one of many, many holes identified over the coming months and years. The security bulletin doesn't seem to be posted (though I honestly didn't look too hard).
In other news... this is funny, and oh-so-true! Read the satirical "Are you a computer security professional?". Hat tip to Anton.
