CWE-352  (opens in a new tab)

How to fix?

Upgrade concrete5/concrete5 to version 8.5.10, 9.1.3 or higher.

Overview

concrete5/concrete5 is a concrete5 open source CMS.

Affected versions of this package are vulnerable to Cross-site Request Forgery (CSRF) due to the lack of a "State" parameter for external Concrete authentication service for users of Concrete who use the "out of the box" core OAuth.

Note: This vulnerability is only exploitable if an attacker knows the Oauth client secret AND the Oauth client is set up without a redirect URL which isn’t possible in v9.
