Found this code inside htaccess - is an Exploit?

This the code I found, seems like the server's pwd is copied over? No idea what it means and what bits I should keep/remove:

# -FrontPage-

IndexIgnore .htaccess */.??* *~ *# */HEADER* */README* */_vti*

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>
<Limit PUT DELETE>
order deny,allow
deny from all
</Limit>
AuthName SITE URL
AuthUserFile /FULL URL/_vti_pvt/service.pwd
AuthGroupFile /FULL URL/_vti_pvt/service.grp

Code (markup):

 

No, it is as it says, for FrontPage. If you are not using FrontPage to manage your site you can actually remove it and deactivate FrontPage Extensions in your control panel.

 

As above, that's coding for FrontPage.

What do you run your site on?

 

Thanks guys, it doesn't use Frontpage...but if I keep it there is should be ok?

 

If your not using Frontpage it will be fine whether you leave it there or not.
