Sensitive Cookie in HTTPS Session Without 'Secure' Attribute in spiral-project/ihatemoney


Reported on

Sep 18th 2021


Secure flag is not implemented on the application

Proof of Concept


The secure flag is an option that can be set by the application server when sending a new cookie to the user within an HTTP Response. The purpose of the secure flag is to prevent cookies from being observed by unauthorized parties due to the transmission of a the cookie in clear text. To accomplish this goal, browsers which support the secure flag will only send cookies with the secure flag when the request is going to a HTTPS page. Said in another way, the browser will not send a cookie with the secure flag set over an unencrypted HTTP request. By setting the secure flag, the browser will prevent the transmission of a cookie over an unencrypted channel.
