Subject: CORE-Impact license bypass

I seem to have stumbled over a bug in Core Impact
licensing mechanisms that will allow anyone to continually use the
Core Impact product even after the license has expired.

This is not a security issue but it is, I feel, either an oversight or
a "feature" which can be abused to utilise the Core Impact product for
longer than designed / desired.

In my "business funded" Core Impact install on this machine, the
license expired at the end of last month and the usualy "Your license
has expired" pop-up appears, however it is easy to re-enable Core to a
working install by merely changing the system date on the PC to say a
month before the product was due to expire. Oops  ;) I guess Core is
using a very simplistic license mechanism.

Emailed CORE two times, 1 week ago, no reply.
