RE: ASP security in HTML pages

On the point of IIS 6.0 disclosing source code, I have already experienced
in one of my test ISP accounts (with FastHosts.com) a situation where the
source code of the Asp.Net pages was being sent directly to the client (i.e.
the *.aspx was being handled as a normal webpage).

Fasthosts refused to give me more details about the circumstances around the
event (like logs, open threads, debug information, etc...) so I was not able
to find more information about what caused the problem in the first place.

Hi all,

I'd like to point out that there have been plenty of ways to get IIS to
reveal ASP source code. Some examples:
http://www.securityfocus.com/bid/2909/info/
http://www.microsoft.com/technet/security/bulletin/MS01-004.mspx
http://www.netscreen.com/services/security/di_resource_center/threat_defin
it
ions.jsp?id=91

As _Hacking Web Applications Exposed_ puts it: "With the track record that
IIS has had in the source disclosure department, it's never a good idea to
assume that someone won't be able to view your source code" (55).

It's sometimes suggested that scripters wrap database connection strings,
encryption keys, and other sensitive information in COM objects to keep
them
private. Are there alternatives? What sorts of strategies do people use to
keep their script contents confidential?

The replies still stand.  The only way the unprocessed
asp page will make it to the client is if there is a
"fatal" flaw/misconfiguration of the IIS server.
Otherwise all request for the file via the http web
server will be processed by the asp dll engine.
However if you request the file via ftp or something
of the sort then yes you will get the unprocesses code
back from the server.

Well, it seems I have not been very shape in my last
posting. I know ASP code is executed on the server's
side, and not in the client's browser (it will just
receive the results of the scriting).

But if a client requests "toto.asp", despite of if
it will receive the "toto.asp" WITHOUT the ASP
scripts, the server has a "full toto.asp" WITH the
asp scripts. So my question was: as the server has
in his directory this "full toto.asp", is there a
way to get the "full toto.asp" from the server?
