A cross site request forgery web vulnerability has been discovered in the official Pluck v4.7.3 content management system. The issue allows remote attackers to manipulate client-side browser to web-application requests to execute service functions via non-expired session credentials. The cross site request forgery vulnerability is located in the cms `var1` parameter of the `admin.php` module POST method request. In the absence of a security token an attacker can execute arbitrary codes against administrator accounts to permanenly delete the pages of the website via panel. Due to the infrastructure the issue becomes more critical without a checkbox to confirm the delete of any page via panel module.
