Cookie Without Secure Flag Detected

Synopsis

Cookie Without Secure Flag Detected

Description

When the `secure` flag is set on a cookie, the browser will prevent it from being sent over a clear text channel (HTTP) and only allow it to be sent when an encrypted channel is used (HTTPS).

The scanner discovered that a cookie was set by the server without the secure flag being set. Although the initial setting of this cookie was via an HTTPS connection, any HTTP link to the same server will result in the cookie being sent in clear text.

Note that if the cookie does not contain sensitive information, the risk of this vulnerability is mitigated.

Solution

If the cookie contains sensitive information, then the server should ensure that the cookie has the `secure` flag set.
