HP-UX Vulnerabilities ( snmp, sendmail, remote network commands )
December 29, 1998 22:00 GMT Number J-022
______________________________________________________________________________
PROBLEM: Three vulnerabilities have been identified by Hewlett-Packard.
1) A SNMP community string in HP OpenView allow access to
certain SNMP variables.
2) sendmail releases are vulnerable to mail spamming.
3) Various remote network commands have security defects.
PLATFORM: HP 9000 series 700/800
DAMAGE: 1) May reduce manageability of affected HP-UX systems.
2) Remote users can compromise system integrity.
3) Users can access unauthorized files / gain increased
privileges.
SOLUTION: Apply patches
______________________________________________________________________________
VULNERABILITY Risk is high. To insure system integrity, the patches should be
ASSESSMENT: applied as soon as possible.

Title: Security Vulnerability with snmp
- -------------------------------------------------------------------------
**REVISED 01** HEWLETT-PACKARD SECURITY BULLETIN: #00088, 30 November 1998
Last revised: 16 December 1998
- -------------------------------------------------------------------------
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: A SNMP community string in HP OpenView allow access to
certain SNMP variables.
PLATFORM: HP 9000 series 700/800.
DAMAGE: May reduce manageability of affected HP-UX systems.
SOLUTION: **REVISED 01** Install the patches listed below.
AVAILABILITY: All patches are available now.
CHANGE SUMMARY: A VirtualVault (VVOS 10.24) patch is available.
- -------------------------------------------------------------------------
I.
A. Background
Reference: ISS X-force SNMP community resource notice,
dated November 2nd, 1998.
A SNMP community string exists in HP OpenView SNMP agent
implementations allowing access to certain SNMP variables.
This may result in limited manageability of affected HP-UX
systems. The system remains operational but will be unable
to respond to some queries from a management server.
This problem is not an OpenView-specific problem, but OpenView
can be affected when communicating with systems that have an
affected agent.
This HP OpenView Emanate SNMP Agent has two revisions currently
supported, release 2.X and 14.X. HP recommends upgrading to
the 14.X release and applying the patch to circumvent this
vulnerability.
B. Fixing the problem
**REVISED 01**
The defect is now fixed such that an unauthorized user can not
use this mechanism. Please install the applicable patch:
Emanate 14.2 version on HP-UX revision 11.00: PHSS_16846
Emanate 14.2 version on HP-UX revision 10.20: PHSS_16845
- ---->>>>Emanate 14.2 version on VVOS revision 10.24: PHSS_17083
Emanate 14.0 version on HP-UX revision 10.0X, 10.10: PHSS_16800
Emanate 14.0 version on HP-UX revision 9.X: PHSS_16799
Solaris 2.3 and 2.4 OpenView Emanate14.0 agent: PSOV_02190
Solaris 2.5.1 and 2.6 OpenView Emanate14.2 agent: PSOV_02191
The Solaris agent patches are available from:
http://ovweb.external.hp.com:80/cpe/patches/emanate/14.x/sparc_2.X.html
CAUTION: Installing any earlier HP OV Emanate patch, or reinstalling
HP OpenView Network Node Manager (NNM) will reverse the
protective effect of the patches listed above. Reinstallation
of the above referenced patch will then be necessary.
This means that if a system administrator deinstalls one of
the earlier patches after installing the security patch, they
will overwrite the security fixes with older software.
The Solaris, HP-UX 9.X, and HP-UX 10.X patches are _NOT_
cumulative. The HP-UX 11.X patch is, however, cumulative
(one that supersedes), and will not be affected in this manner.
- --->>> Due to the security features on the VirtualVault system using VVOS
- --->>> 10.24, the system is not vulnerable to the stated access from the
- --->>> OUTSIDE or Internet. The vulnerability only exists on the INSIDE
- --->>> or internal network.

I.
A. Background
Some important features provided by 8.8.6 includes a new group
of rulesets to avoid mail "spamming" (i.e., sending of unsolicited
mail to large number of users) and to prevent mail "spammers"
from using your host as a mail relay point.
Sendmail 8.8.6 provides four new named rulesets which can be used
to check and reject abusive mail messages.
Patches are available from the Electronic Support Center (ESC)
patch hub for HP-UX 10.20, 10.30, and 11.0. An upgrade is
available for HP-UX 10.00, 10.01, and 10.10. Hewlett-Packard
recommends installing sendmail 8.8.6 for HP-UX 10.00, 10.01,
and 10.10 as an optional version upgrade. This upgrade is
not available from the Electronic Support Center (ESC) patch
hub, but from:
http://www.software.hp.com/software/HPsoftware/Sendmail/index.html
There are numerous new configuration options available and various
issues involved in upgrading to Sendmail 8.8.6. The URL above
provides additional information regarding the impact of the
upgrade.
