If you have stumbled upon a web page that displays a plain white background with a list of files and the heading "Index of /view.shtml", you have likely encountered a serious web server misconfiguration. While it may look like a simple directory listing, the presence of an index of view.shtml entry is a digital red flag for developers, hackers, and SEO specialists alike.

In this deep-dive article, we will explore what view.shtml is, why an "index of" listing appears, the security implications of exposing this file, and how to fix it before malicious actors exploit it.

Open IIS Manager, select the directory, double-click "Directory Browsing," and select "Disabled" in the Actions pane.

If an attacker attempted a directory traversal attack (../../view.shtml/) and the server responded with an index listing, it confirms that SSI execution is possible outside the web root—a severe vulnerability.

When you see Index of /view.shtml, you are looking at directory listing (also called directory indexing). This occurs when:

Instead of returning a 403 Forbidden error, the server kindly generates an HTML list of all files inside that directory. For example:

Index of /view.shtml
[PARENTDIR] Parent Directory
[ ] config.inc
[ ] passwords.txt
[ ] view.shtml
[ ] logs/

If you see this, it means the server believes /view.shtml is a directory, not a file.

Configure your web server to deny directory browsing.

For Apache (.htaccess or httpd.conf):

Options -Indexes

Place this in the directory where view.shtml resides or in the root .htaccess file. Then restart Apache.

For Nginx: In your server block, set:

autoindex off;

Then reload Nginx: sudo systemctl reload nginx

For IIS: Open IIS Manager → Select your site → Directory Browsing → Disable.

Add the following line to the relevant configuration file or an .htaccess file inside the directory:

Options -Indexes

If you need to disable indexing globally, ensure your <Directory> block does not include +Indexes. To also prevent access to .shtml source, add:

<Files "*.shtml">
    ForceType text/html
</Files>

In many cases, website owners actually intend to serve a default SHTML page when a user visits a directory. The proper configuration is to use DirectoryIndex (Apache) or index (Nginx) to load view.shtml as the default page, not as a directory listing.

Correct Apache configuration:

DirectoryIndex view.shtml index.shtml index.html

With this setting, when a user visits https://example.com/folder/, the server automatically serves folder/view.shtml instead of showing an "Index of" page.

If view.shtml is not parsed correctly by the server (or if the server misinterprets a directory as requiring SSI parsing), an attacker might download the raw source code. This reveals file paths, database connection strings, or custom functions hidden in SSI directives.
