Daloradius Cross-Site Request Forgery

daloRADIUS is an open source RADIUS web management application. daloRadius 1.3 and prior are vulnerable to a combination cross site scripting (XSS) and cross site request forgery (CSRF) vulnerability which leads to account takeover in the mng-del.php file because of an unescaped variable reflected in the DOM on line 116. This issue has been addressed in commit `ec3b4a419e`. Users are advised to manually apply the commit in order to mitigate this issue. Users may also mitigate this issue with in two parts 1) The CSRF vulnerability can be mitigated by making the daloRadius session cookie to samesite=Lax or by the implimentation of a CSRF token in all forms. 2) The XSS vulnerability may be mitigated by escaping it or by introducing a Content-Security policy.

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.
