SSRT3647 ProCurve 5300 series and RPC worms
-----------------------------------------------------------------
NOTICE: There are no restrictions for distribution of this
Bulletin provided that it remains complete and intact.
The information in the following Security Bulletin should be
acted upon as soon as possible. Hewlett-Packard Company will
not be liable for any consequences to any customer resulting
from customer's failure to fully implement instructions in this
Security Bulletin as soon as possible.
-----------------------------------------------------------------
PROBLEM: HP ProCurve Switches can exhibit deteriorating
performance and fail to function in presence of RPC
worms such as Welchia and Blaster.
IMPACT: Potential for denial of service.
PLATFORM: Only HP ProCurve Switch 5304XL (J4850A), 5348XL
(J4849A), 5372XL (J4848A), 5308XL (J4819A).
SOLUTION: Upgrade switch software to E.07.40 or subsequent.
MANUAL ACTIONS: Non-HP-UX only
This is not an HP-UX issue.
Install firmware E.07.40, or newer.
AVAILABILITY: The firmware is available now. (See below for
details).
-----------------------------------------------------------------
A. Background
The HP ProCurve Switches potentially suffer an adverse
reaction to the presence of the Blaster/Welchia worms.
Networking performance deteriorates resulting in the
appearance of a Denial of Service for connected end nodes,
generally running Microsoft Windows operating systems.
Only the following HP ProCurve Switches are affected:
5304XL (J4850A), 5348XL (J4849A), 5372XL (J4848A),
5308XL (J4819A).
NOTE: This problem does not directly impact HP-UX, MPE/iX,
HP NonStop Servers, HP OpenVMS, nor HP Tru64
UNIX/Trucluster Server.
B. Recommended solution
Several steps need to be taken to mitigate the problem.
1. Locate and remove worms from infected and connected network
clients. To accomplish that task, download the Snort*
utility which is designed to identify a network client
infected by the Blaster and/or Welchia worms.
http://www.snort.org/
Follow the recommended instructions provided to install and
to locate and remove these worms from your network.
The following link provides some details of how to detect
traffic that is caused by such worms and the data from this
link can be used to compare to the traces that you capture
off your network.

detecting.traffic.due.to.rpc.worms.html
2. Administrators should take actions to prevent worm
infiltrations on the network by ensuing that the latest
patches for security vulnerabilities are applied to end
clients via Microsoft Security releases.
http://v4.windowsupdate.microsoft.com
3. Download and install the new switch software version E.07.40
or subsequent from:
http://www.hp.com/rnd/software/switches.htm
If further assistance is required, contact your local
ProCurve Customer Care Center, or visit their web site at:
http://www.hp.com/rnd/assistance/assistance.htm
