Vulnerability discussion

Cookies are used to exchange data between the web server and the client. Cookies, such as a session cookie, may contain session information and user credentials used to maintain a persistent connection between the user and the hosted application since HTTP/HTTPS is a stateless protocol. When the cookie parameters are not set properly (i.e., domain and path parameters), cookies can be shared within hosted applications residing on the same web server or to applications hosted on different web servers residing on the same domain.

Check content

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" If "HttpOnly" "secure" is not configured, this is a finding. "Header always edit Set-Cookie ^(.*)$ $1;HttpOnly;secure" Review the code. If, when creating cookies, the following is not occurring, this is a finding: function setCookie() { document.cookie = "ALEPH_SESSION_ID = $SESS; path = /; secure"; }

Fix text

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" Add or configure the following line: "Header always edit Set-Cookie ^(.*)$ $1;HttpOnly;secure" Add the "secure" attribute to the JavaScript set cookie in any application code: function setCookie() { document.cookie = "ALEPH_SESSION_ID = $SESS; path = /; secure"; } HttpOnly cannot be used since by definition this is a cookie set by JavaScript. Restart www_server and Apache.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
