(in versions v4 r2 through v2 r2)
Title
Cookies exchanged between the web server and the client, such as session cookies, must have cookie properties set to force the encryption of cookies. (Cat II impact)
Discussion
Cookies can be sent to a client using TLS/SSL to encrypt the cookies, but TLS/SSL is not used by every hosted application since the data being displayed does not require the encryption of the transmission. To safeguard against cookies, especially session cookies, being sent in plaintext, a cookie can be encrypted before transmission. To force a cookie to be encrypted before transmission, the cookie Secure property can be set.
Check Content
Review the web server documentation and deployed configuration to verify that cookies are encrypted before transmission. If the web server is not configured to encrypt cookies, this is a finding.
Fix Text
Configure the web server to encrypt cookies before transmission.
