    I've got a problem.  I've used the handy dandy unitools (by Roelof
    Temmingh), Unicodeloader.pl script to upload its upload.asp and upload.inc
    files to the victim IIS server with the various IIS folder traversal
    vulnerabilities.  This worked like a charm every time via port 80.
    
    I now have a client with an IIS server on port 443 with the msadc.dll
    vulnerability.  I was able to take advantage of the vulnerability to copy
    cmd.exe into the /scripts directory.  We modified the Unicodeloader.pl
    script to use the now available cmd.exe.
    
    In order to run the utility, I attach via Stunnel.  The upload works and
    both the upload.asp and the upload.inc get up the IIS servers webroot.  The
    only problem is that in the transferred upload.inc script, every instance of
    + is replaced with a space.
    
    Not sure why this is happening.  All I know is that when I upload the
    upload.inc file via straight port 80 it's fine and going through Stunnel the
    + is replaced with a space.
    
    My goal is to get Netcat up there (of course).
    
    Does anybody know what Is going on here and what I can do to get around it?
