Unisys ClearPath halt with nmap scan



3rd Oct 2002 [SBWID-5725]
COMMAND

	Unisys ClearPath halt with nmap scan

SYSTEMS AFFECTED

	Unisys ClearPath

PROBLEM

	Jonathan G. Lampe [jonathan@stdnet.com] found :
	

	Unisys "Clearpath" mainframes are very sensitive to the probes  of  nmap
	and  similar  programs.  Basically,  by  only  port-scanning  (not  even
	fingerprinting), you can cause the entire machine  to  seize  up.  (Yes,
	the whole machine...not just a job or the TCP/IP device.)
	

	--snapp--
	

	Say hello to my little friend: "nmapnt 10.0.0.8  -p  1-1023  -T  Normal"
	(If that doesn't work, make it less polite. Watch the  "SPO"  for  added
	fun.)

SOLUTION
