We are still in the process of determining which other HP
Procurve products are subject to these vulnerabilities.
We have created fixes for products below which will resolve
these issues. See Section C below.
Customers can download these patches in the form of software
upgrades at:

HP TopTools Remote Control Card
---------------------------------------------------------
TopTools Remote Control (TTRC) card, rev. 2.0. (product P1218A)
has an SNMP MIB defect. This is fixed in firmware version
B.03.02 available at:
http://h20004.www2.hp.com/keeper_rnotes/bsdmatrix/matrix62319.html
---------------------------------------------------------
JetDirect Firmware
---------------------------------------------------------
JetDirect Firmware Version State
========================== =====
X.08.32 and lower VULNERABLE
(where X = A through K)
X.21.00 and higher NOT vulnerable
(where X = L through P)
FIX STATUS: HP is working on a firmware fix.
WORKAROUND: Change the set-community-name and use the
Access Control List as described in "HP JetDirect Print
Servers - Making HP JetDirect Print Servers Secure on
the Network":
http://www.hp.com/cposupport/networking/support_doc/
bpj05999.html#P88_10129
LIMITING THE VULNERABILITY
SNMPv1 security relies on the set community name. It is
important that a set-community-name be configured on the
JetDirect device and that it be kept secret.
JetDirect Print Servers offer an Access Control List that
can be used to specify which hosts can make SNMP
configuration changes to JetDirect Print Servers.
The steps above can help prevent exploitation of the
vulnerability. To eliminate the vulnerability before a fix
is available SNMP can be disabled on the JetDirect device.
DISABLING SNMP ON A JETDIRECT PRINT SERVER
1. Update the firmware to the highest level as described in
the JetDirect Upgrade Instructions document:
http://www.hp.com/cposupport/networking/support_doc/bpj06917.html
NOTE: Disabling SNMP may affect device discovery and port
monitors that use SNMP to get status on the device.
Use this feature with care.
2. Telnet to the JetDirect device (on the latest firmware)
and type:
snmp-config: 0
quit
This will completely disable SNMP on the JetDirect device.
HP always recommends upgrading JetDirect firmware for the
latest bug fixes and security benefits. The upgrade firmware
and download utility are available free of charge:
http://www.hp.com/cposupport/networking/support_doc/bpj06917.html
The following is a list of JetDirect Product Numbers
that can be freely upgraded to X.08.32 or X.21.00 or
higher firmware. The latest firmware revision available
for download is given. For example, the latest firmware
revision for the J3110A is G.08.32.

The HP OC SS7 (OpenCall) products J3362A and J5938A running
on HP-UX releases 10.20 and 11.X are not vulnerable if the
applicable HP-UX patch listed above is installed.
============================================================
NOTE: The patches are labeled OV (OpenView). However, the
patches are also applicable to systems that are _NOT_
running OpenView.
============================================================
Workaround for HP-UX Systems:
If a patch is not available for your platform or you cannot
install an available patch, snmpd and snmpdm can be disabled
by removing their entries from /etc/services and removing the
execute permissions from /usr/sbin/snmpd and /usr/sbin/snmpdm.
