Hi.

Speaking of weird problems. I was falling about a problem and I am not
sure if I am too stupid :) or there is a bug. If it is a bug, I would
put it into security bug bucket.

I have the following access.conf:

<snip>

# This should be changed to whatever you set DocumentRoot to.
<Directory /usr/local/www/data>
Options Indexes IncludesNOEXEC FollowSymLinks
<Limit GET>
order allow,deny
allow from all
</Limit>
</Directory>

<snip>
As this shows I set IncludesNOEXEC, which should allow me to do
Server Side Includes, but no CGI-BIN or external programs.

Now I have here this webpage:

<html>
<head>
<title>Ulf's empty homepage</title>
</head>

<body>
I have no time to make something up here, but I would like to give you
some links to memory specs:) <p>

..... [Stuff deleted]

<hr>

<!--#config timefmt="Updated %B %e, %Y at %H:%M (%Z)" -->
<!--#exec cgi="/cgi-bin/pagecount" --><br>
<!--#echo var="LAST_MODIFIED" --><br>

<hr>
<pre><!--#exec cmd="ls -als /tmp" --></pre><br>
</body>
</html>

------
As you see I have 1 CGI, 1 external program and 1 ECHO. If I know access
this via http://server/ulf/index.html, the server executes the ECHO and
don't allow the CGI and external program. It gives a message like
"An error occured while executing this directive"

But now, if I access this page via http://server/~ulf/index.html it executes
everything regardless of "Option IncludeNOEXEC". Has anyone seens this too?

Open for everything. And yes you can call me stupid, if it is in the manual,
but I couldn't find anything. I looked into the source code and I think
it might be a bug.

Ulf. :)
