server side includes on .htm risks?

server side includes on .htm risks?

am 11.01.2008 18:25:00 von jason

I have a user who is asking wants to enable server side include processing on
..htm and .html files.
IIS6 says is secure by default, so it makes me leery changing from default,
plus its is just more admin work to maintain across servers.

What are the risks, security and others that can result in add ssi
processing on .htm and html files?

and what verbs should be allowed?

thanks

Hi,

I think this article covers some of your questions:

"Using server side include directives in .html pages, and its caveats"
http://www.gafvert.info/iis/article/process_html_as_shtml.ht m

Basically, it does not matter if the extension is .htm or .shtm if you know
all files with that extension will need to go thru the server side
processing. But if most .htm files are static files, there are some
advantages of having it being handled as static pages.

Only add the verbs you need, obviously.

Hi Jason,

Kristofer's blog gives perfect answer of the question. The only supplement
of mine is it does bring the risk if both SSI and Parent Path are enabled
on web server. Please refer to:

332117 Enable Parent Paths Is Disabled by Default in IIS 6.0
http://support.microsoft.com/default.aspx?scid=kb;EN-US;3321 17

Thanks.

Sincerely,
