Discussion

Resource mapping is the process of tying a particular file type to a process in the web server that can serve that type of file to a requesting client and to identify which file types are not to be delivered to a client. By not specifying which files can and cannot be served to a user, the web server could deliver to a user web server configuration files, log files, password files, etc. The web server must only allow hosted application file types to be served to a user, and all other types must be disabled.

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: 
 
# apachectl -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT="/etc/httpd"
-D SERVER_CONFIG_FILE="conf/httpd.conf"

Note: The apachectl front end is the preferred method for locating the Apache httpd file. For some Linux distributions "apache2ctl -V" or  "httpd -V" can also be used. 
 
If "Action" or "AddHandler" exist and they configure .exe, .dll, .com, .bat, or .csh, or any other shell as a viewer for documents, this is a finding. 
 
If this is not documented and approved by the Information System Security Officer (ISSO), this is a finding.
