<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Flask is a lightweight WSGI web application framework. It is designed to make getting started quick and easy, with the ability to scale up to complex applications. It began as a simple wrapper around Werkzeug and Jinja and has become one of the most popular Python web application frameworks.
|
|
|
|
Security Fix(es):
|
|
|
|
Flask is a lightweight WSGI web application framework. When all of the following conditions are met, a response containing data intended for one client may be cached and subsequently sent by the proxy to other clients. If the proxy also caches `Set-Cookie` headers, it may send one client's `session` cookie to other clients. The severity depends on the application's use of the session and the proxy's behavior regarding cookies. The risk depends on all these conditions being met.
|
|
|
|
1. The application must be hosted behind a caching proxy that does not strip cookies or ignore responses with cookies.
|
|
2. The application sets `session.permanent = True`
|
|
3. The application does not access or modify the session at any point during a request.
|
|
4. `SESSION_REFRESH_EACH_REQUEST` enabled (the default).
|
|
5. The application does not set a `Cache-Control` header to indicate that a page is private or should not be cached.
|
|
|
|
This happens because vulnerable versions of Flask only set the `Vary: Cookie` header when the session is accessed or modified, not when it is refreshed (re-sent to update the expiration) without being accessed or modified. This issue has been fixed in versions 2.3.2 and 2.2.5.(CVE-2023-30861)</Note>
