Details
Security: Require ADMIN for ?flush=1
Flushing the various manifests (class, template, config) is performed through a GET
parameter (flush=1). Since this action requires more server resources than normal requests,
it can facilitate denial-of-service attacks.
To prevent this, main.php now checks and only allows the flush parameter in the following cases:
- The environment is in "dev mode"
- A user is logged in with ADMIN permissions
- An error occurs during startup
This applies to both flush=1 and flush=all (technically we only check for the existence of any parameter value)
but only through web requests made through main.php - CLI requests, or any other request that goes through
a custom start up script will still process all flush requests as normal.
Upgrading
-
If you have created your own composite database fields, then you should amend the setValue() to allow the passing of an object (usually DataObject) as well as an array.
-
If you have provided your own startup scripts (ones that include core/Core.php) that can be accessed via a web request, you should ensure that you limit use of the flush parameter
