Cookies exchanged between the Apache web server and the client, such as session cookies, must have cookie properties set to prohibit client-side scripts from reading the cookie data.

Description
A cookie can be read by client-side scripts easily if cookie properties are not set properly. By allowing cookies to be read by the client-side scripts, information such as session identifiers could be compromised and used by an attacker who intercepts the cookie. Setting cookie properties (i.e., HttpOnly property) to disallow client-side scripts from reading cookies better protects the information inside the cookie.

In a command line, run "httpd -M \| grep -i session_cookie_module". Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V \| egrep -i 'httpd_root\|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Search for the directive "Session" in the "httpd.conf" file: # cat //httpd.conf \| grep -i "Session" If the "Session" and "SessionCookieName" directives are not present, this is a finding. If "Session" is not set to "on" and "SessionCookieName" does not contain "httpOnly" and "secure", this is a finding.

In a command line, run "httpd -M | grep -i session_cookie_module".

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file:

# httpd -V | egrep -i 'httpd_root|server_config_file'
-D HTTPD_ROOT="/etc/httpd"
-D SERVER_CONFIG_FILE="conf/httpd.conf"

Search for the directive "Session" in the "httpd.conf" file:

# cat //httpd.conf | grep -i "Session"

If the "Session" and "SessionCookieName" directives are not present, this is a finding.

If "Session" is not set to "on" and "SessionCookieName" does not contain "httpOnly" and "secure", this is a finding.

Determine the location of the "HTTPD_ROOT" directory and the "httpd.conf" file: # httpd -V \| egrep -i 'httpd_root\|server_config_file' -D HTTPD_ROOT="/etc/httpd" -D SERVER_CONFIG_FILE="conf/httpd.conf" Set "Session" to "on". Ensure the "SessionCookieName" directive includes "httpOnly" and "secure".
