An issue was discovered in MDaemon before 20.0.4. Remote Administration allows an attacker to perform a fixation of the anti-CSRF token. In order to exploit this issue, the user has to click on a malicious URL provided by the attacker and successfully authenticate into the application. Having the value of the anti-CSRF token, the attacker may trick the user into visiting his malicious page and performing any request with the privileges of attacked user.
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.
