RE: nikto, n-stealth can crash the web-server?

Depends on your definition of crash. Nikto can cause the Apache process to
restart if Apache is not configured correctly. The number of requests coming
in can overwhelm Apache. Again, if Apache is misconfigured, the number of
requests and subsequent spawning of child processes can cause the load
average to spike causing the OS to be unresponsive.

Subject: nikto, n-stealth can crash the web-server?

Hello to all,


I'm trying to find out if web-scanners like n-stealth or nikto can
crash the web-server and why. By searching in the scan-db of nikto I
found no tests that could cause a buffer overflow or DoS. Maybe the
flooding of requests itself can cause the server to crash?!

When you ever had the experience that one of the scanners has crashed a
server I would really like to know which test has caused that. When I'm
going to test the productive web-servers I must be very sure they are
still available for the users of the web-applications.

By the way, is there any comparison available for both scanners? They
really seem to be very similar in what they do?!


Thanx, Maze
