I'm not sure how this well known feature of Metaframe is a security hole. If
you are really that worried about security you probably shouldn't be mapping
drives (or anything else).
 
You can also control read/write access to all client drives using the
webica.ini file described in CTX568194

Hi All,
 
I was recently enlightened on what I consider a fairly major security
loop-hole in Metaframe...
 
Maybe the rest already know....
 
The wonderful feature of mapping your local hard drives.....you can also map
the network drives of the client via hidden shares...this could be really
bad...right???
 
I personally don't like security by obscurity.
 
I raised the issue to Citrix....but they didn't say much.  
 
I suggested they modify the client and Management console to allow to
allow/deny each drive separately to tighten up this security risk.
 
Am I crazy or do you see where I am coming from?
 
Perhaps you might want to let Citrix know too...
