      Title:  Sec. Vulnerability in HP OpenView EMANATE14.2

 -----------------------------------------------------------------
 HEWLETT-PACKARD COMPANY SECURITY BULLETIN: HPSBUX0208-208
 Originally issued: 08 Aug. 2002
 -----------------------------------------------------------------

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: The HP OpenView EMANATE14.2 read-write community string
         may be exposed.

PLATFORM: HP 9000 Series 700 and Series 800 running HP-UX
          and EMANATE14.2.
          Solaris 2.6,7,8 running EMANATE14.2.
          Win NT/2k running EMANATE14.2.

DAMAGE:   Possible unauthorized access, denial of service.

SOLUTION: Apply the appropriate patch and restrict access to
          the community name.

Win NT/2k:       NNM_00936  EMANATE14.2 snmpModules of SNMPv2 MIB
hp-ux 10.20:     PHSS_27569 EMANATE14.2 snmpModules of SNMPv2 MIB
hp-ux 11.X:      PHSS_27570 EMANATE14.2 snmpModules of SNMPv2 MIB
Solaris 2.6,7,8: PSOV_03193 EMANATE14.2 snmpModules of SNMPv2 MIB


MANUAL ACTIONS: Restrict access to the community name by
                modifying snmpd.conf.

AVAILABILITY:  The patches are available now.
 ------------------------------------------------------------------ 
 A. Background
    There are two parts to the problem.  The patches address the
    'read-only' community access.   Also, it is possible to guess
    the community-name.  The solution for that part of the problem
    is to restrict access to the community name.

 B. Recommended solution
    1. Install the appropriate patch:

Win NT/2k:       NNM_00936  EMANATE14.2 snmpModules of SNMPv2 MIB
hp-ux 10.20:     PHSS_27569 EMANATE14.2 snmpModules of SNMPv2 MIB
hp-ux 11.X:      PHSS_27570 EMANATE14.2 snmpModules of SNMPv2 MIB
Solaris 2.6,7,8: PSOV_03193 EMANATE14.2 snmpModules of SNMPv2 MIB

       The patches are available from
       http://support.openview.hp.com/cpe/patches/

    2. Setup a VIEW in snmpd.conf to restrict/deny access to the
       communityGroup.  For example:

# The VIEW: qualifier further restricts access using the community
# name to the sub-set of the agent's supported MIB identified by
# the space list of "MIB view sub-trees". A view sub-tree may be
# either the object identifier (1.3.6.1.2.1.1) or object name
# (system) of the MIB sub-tree to be included. The '-' character
# may be used to exclude an oid/name from the view. For example,
#
# You can resolve this issue by adding a VIEW: qualifier to each
# line containing a get-community-name.
# The least restrictive VIEW: qualifier which denies access to the
# communityTable is:
get-community-name: yyyyyy VIEW: 1.3.6.1 -communityMIB
