Summary:
Attempted .htgroup access via web

--
Impact:
Attempt to gain information on group access permissions on a webserver

--
Detailed Information:
This is an attempt to gain intelligence on the user and administration groups used on a webserver. The .htgroup file lists the groups allowed to access resources on a webserver. The attacker could possibly gain information needed for other attacks on the host.

--
Attack Scenarios:
The attacker can make a standard HTTP request that contains '.htgroup'in the URI.

--
Ease of Attack:
Simple HTTP request.

--
False Positives:
None Known

--
False Negatives:
None Known

--
Corrective Action:

Webservers should not be allowed to view or execute files and binaries outside of it's designated web root or cgi-bin. Disallowing viewing of this file via a URI is suggested. For Apache webservers add the following to httpd.conf and restart the server.

<Files ~ "^\.ht">
    Order allow,deny
    Deny from all
</Files>
