Climatix BACnet/IP Communication Module Cross Site Scripting

`I. VULNERABILITIES  
-------------------------  
  
1. Reflected XSS Attack vulnerability in Climatix BACnet/IP communication  
module from Siemens  
  
2. Unrestricted upload of files  
  
  
II. BACKGROUND  
-------------------------  
  
BACnet/IP communication modules help to integrate controller types POL6XX  
of the Climatix family into BACnet networks  
  
  
III. DESCRIPTION  
-------------------------  
  
1. XSS,Has been detected Reflected XSS vulnerability  
  
http://IPDIRECTION/bgi/dumpfile.dll?")</b><script>alert("hacked");</script>  
  
  
2. Unrestricted upload of files:  
  
http://IPDIRECTION/bgi/filemanager.dll#upload  
  
V. BUSINESS IMPACT  
-------------------------  
  
An attacker can execute arbitrary HTML or script code in a targeted  
user's browser, that allows the execution of arbitrary HTML/script  
code to be executed in the context of the victim user's browser  
allowing Cookie Theft/Session Hijacking, thus enabling full access the  
box.  
  
The box can be compromised due to upload of files and execution.  
  
  
VI. SYSTEMS AFFECTED  
-------------------------  
  
Climatix BACnet/IP communication module: All versions < V10.34  
  
  
VII. SOLUTION  
-------------------------  
  
Siemens provides firmware update Climatix BACnet/IP communication module  
V10.34 which fixes the vulnerability (XSS).  
  
The new firmware update includes further security improvements (e.g. web  
server  
authentication enabled by default) due to vulnerabilities founded like  
uncontrolled upload of files and unrestricted execution of dangerous  
functions like "shell.exe" and "cmd.exe".
