We just tested the Sioux (Apache DoS) bug on: <> IIS 3.0 (Service Pack 3) causes immediate jump to 100% CPU for approx. 5 seconds multiple attacks can keep the CPU in the 90% range <> IIS 4.0 (Service Pack 3) causes immediate jump to 80% CPU for approx. a half second multiple attacks DO NOT cause more thank 40% sustained CPU range <> Apache 1.1.1 (Unix) (Caldera OpenLinux) causes jump to 66% CPU for each get request and attempts to use all available swap space for memory. Can be DoS'd easily. <> WebSitePro 2.3.4 (Service Pack 3) causes immediate jump to 99% CPU for approx. 5 seconds unknown if DoS would be possible for multiple attacks Regards, Jonathan Freeman -----Original Message----- From: Jamie Orzechowski <mhz () RECORDER CA> To: BUGTRAQ () netspace org <BUGTRAQ () netspace org> Date: Tuesday, August 11, 1998 1:39 PM Subject: Apache DoS Attack
I tried the sioux bug on Website c2.3 for NT and I noticed in the processes that the CPU jumped upto 99% ... any ideas?
