Concrete CMS 9 before 9.2.3 is vulnerable to Cross Site Request Forgery (CSRF) via /ccm/system/dialogs/logs/delete_all/submit. An attacker can force an admin user to delete server report logs on a web application to which they are currently authenticated.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
