Usualtoolcms Cross-Site Request Forgery

An issue was discovered in UsualToolCMS 8.0. cmsadmin/a_sqlbackx.php?t=sql allows CSRF attacks that can execute SQL statements, and consequently execute arbitrary PHP code by writing that code into a .php file. (2019-01-12, CVE-2019-6244)

UsualToolCMS 8.0 allows CSRF for adding a user account via the cmsadmin/a_adminx.php?x=a URI. (2018-10-17, CVE-2018-18422)

The absence of Anti-CSRF tokens may lead to a Cross-Site Request Forgery attack that can result in executing a specific application action as another logged in user, e.g. steal their account by changing their email and password or silently adding a new admin user account when executed from the administrator account.

The attacker may copy one of your web application forms, e.g. email/password change form.

The webpage will contain a form with the exact set of fields as the original application but with input values already provided and the submit button replaced with a Javascript code causing auto-submission. When the page is accessed the form will be immediately submitted and page contents replaced with a valid content or a redirect to your original application.

One of your application users who is already logged in can be then tricked to navigate to such malicious page e.g. by clicking a link in a phishing email, and the pre-populated form content will be submitted to your application like it would be submitted by your user.
