Can you, please, provide example of such server? Fatih Ozavci reported
similar problem with Checkpoint and Halfwidth/Fullwidth Unicode,
potential attack vector was IIS with .Net framework, in this case IIS
seems not to be exploitable.
Blaming IPS it does not detect attack which is impossible in-the-wild is
nonsense. Blaming corporate-level IPS doesn't detect attack against SOHO
web server is acceptable nonsense :)
