AXON PBX 2.02 DLL Hijacking

`Aloha,  
  
*Summary:*  
AXON PBX contains a DLL loading vulnerability that could allow an  
unauthenticated, remote attacker to execute arbitrary code on the targeted  
system. The vulnerability exists due to some DLL file is loaded by  
'pbxsetup.exe' improperly. And it allows an attacker to load this DLL file  
of the attackeras choosing that could execute arbitrary code and gain  
elevated privileges without the user's knowledge.

*Affected Product:* AXON PBX 2.02 (pbxsetup.exe)  
  
*Tested on:* Windows 7 (64-bit)  
  
*Impact:*  
Attacker can exploit this vulnerability to load a DLL file of the  
attacker's choosing that could execute arbitrary code. This may help  
attacker to successfully exploit the system if user creates shell as a DLL.  
  
*Vulnerability Scoring Details:*  
The vulnerability classification has been performed by using the CVSSv2  
scoring system (http://www.first.org/cvss/).  
Base Score: 7.2 (AV:A/AC:L/Au:N/C:C/I:C/A:C)  
  
*Proof of concept/demonstration:*
