Directory options directives are directives that can be applied to further restrict access to file and directories. The Options directive controls which server features are available in a particular directory. The ExecCGI option controls the execution of CGI scripts using mod_cgi. This needs to be restricted to only the directory intended for script execution.

Check Text ( C-33613r2_chk )
Search for the unnecessary CGI programs which may be found in the directories configured with ScriptAlias, Script or other Script* directives. Often, CGI directories are named cgi-bin. Also, CGI AddHandler or SetHandler directives may also be in use for specific handlers such as perl, python and PHP.

To search the http.conf file for Options enter the following command:

grep "Options" /usr/local/apache2/conf/httpd.conf.
For every instance of “Options” in the httpd.conf file other than where CGI files are specifically located, the “ExecCGI” must be explicitly disabled (-ExecCGI).

If the value for Options is not returned with a “-ExecCGI” , this is a finding.
Fix Text (F-29240r1_fix)
Locate any cgi-bin files and directories enabled in the Apache configuration via Script, ScriptAlias or other Script* directives.

Remove the printenv default CGI in cgi-bin directory if it is installed.

rm $APACHE_PREFIX/cgi-bin/printenv.

Remove the test-cgi file from the cgi-bin directory if it is installed.

rm $APACHE_PREFIX/cgi-bin/test-cgi.

Review and remove any other cgi-bin files which are not needed for business purposes.
