× Few antiviral products inadequately detect 3proxy as Trojan.Daemonize, Backdoor.Daemonize, etc and many detect 3proxy as a PUA (potentially unwanted program). It may cause browser warning on download page. 3proxy is not trojan or backdoor and contains no functionality except described in documentation. Clear explanation of this fact is given, for example, in Microsoft's article.

Vendor: Hewlett-Packard
Application:  Network  Node Manager 7.50 Remote Console
	under Microsoft	Windows XP SP2.
Vulnerability: Local
Vulnerability Level: High
Author: 3APA3A <[email protected]>, SecurityVulns.com
Impact: privilege escalation of any unprivileged user to
	Local System or another user's account.


NNM  Remote  Console  is  remote  administration  tool  for Network Node
Manager.  Unlike  the  rest  of  NNM  it's  installed on administrator's
workstation.  7.50  is  latest version of NNM Remote Console, because it
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 (and may be
another OV components, not tested) 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
admin user).

And worse: there is a service installed into HP Open View folder,

HP Open View Shared Trace Service installed into
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.


1. Rename  ovtrcsvc.exe to ovtrcsvc.old
2. Replace  ovtrcsvc.exe  with  any  application of your choice and
restart system.


Restore  permission  inheritance  from  parent  folder  for  "C:\Program
Files\HP OpenView\".
