Sensitive Cookie in HTTPS Session Without 'Secure' Attribute in thorsten/phpmyfaq


Reported on

Oct 16th 2021

✍️ Description

The secure flag is not set for session cookie in the application.

Proof of Concept

Check this for POC: Image


If the secure flag is set on a cookie, then browsers will not submit the cookie in any requests that use an unencrypted HTTP connection, thereby preventing the cookie from being trivially intercepted by an attacker monitoring network traffic. If the secure flag is not set, then the cookie will be transmitted in clear-text if the user visits any HTTP URLs within the cookie's scope. An attacker may be able to induce this event by feeding a user suitable links, either directly or via another web site.

This is true if you run phpMyFAQ over HTTP, it's flagged as secure if you run phpMyFAQ via HTTPS.
