Original Entry Date: Feb 8 2007

Impact:
Root access via local system, User access via local system

Vendor Confirmed: Yes Exploit Included: Yes
|
Version(s): Remote Console version 7.50, 7.51, 7.53

Description:
A vulnerability was reported in OpenView Network Node Manager. A local user can obtain elevated privileges on Windows-based systems.
The console component installs on Windows-based systems with insecure folder permissions, granting 'Full Control' privileges to the 'Everyone' group for the 'C:\Program Files\HP OpenView' directory and subdirectories. As a result, a local user can modify files in the directory to cause arbitrary code to be executed when the target user runs OpenView. A local user can also modify the HP Open View Shared Trace Service ('C:\Program Files\HP OpenView\bin\ovtrcsvc.exe') to cause arbitrary code to be executed with Local System privileges.
The vendor was notified on September 11, 2006.
3APA3A of SecurityVulns.com reported this vulnerability.

Impact:

CVE: CVE-2007-0819
Intro:
NNM Remote Console is remote administration tool for HP Network Node
Manager (NNM). Unlike the rest of NNM, it's installed on administrator's
workstation. 7.50 is the latest version of NNM Remote Console, because
console installation can not be upgraded to 7.51.
Vulnerability Description:
The bug is very simple: insecure installation folder permissions. During
installation of HP Open View Network Node Manager Console this commands
is performed:
C:\WINDOWS\system32\cmd.exe /C CALL cacls "C:\Program Files\HP OpenView" /T /C /P Everyone:F < "C:\Program Files\HP OpenView\yes.txt"
>> "C:\Program Files\HP OpenView\log\setup.log"
This command recursively changes access permissions for
C:\Program Files\HP OpenView
folder to
Everyone:Full Control.
It makes it possible for any local user to replace any of HP Open View
executable files or ActiveX components with trojaned/backdoored ones and
gain permissions of user running any of Open View applications (usually
network administrator user).
And worse: there is service installed into HP Open View folder, namely
HP Open View Shared Trace Service
with executable
C:\Program Files\HP OpenView\bin\ovtrcsvc.exe
It's executed with highest possible Local System account. It makes it
possible for any local user to overwrite service executable and obtain
Local System privileges.
Exploit:
1. Rename ovtrcsvc.exe to ovtrcsvc.old
2. Replace ovtrcsvc.exe with any application of your choice and
restart system.
3. Reboot (or wait for reboot).
Workaround:
Restore permission inheritance from parent folder for "C:\Program
Files\HP OpenView\".
