FortiGate SSLVPN Update-Empfehlung

Update, Nov 2020:

More than a year after Fortinet described this SSLVPN vulnerability, it gets new attention. A few days ago a list of IPs and domain names of vulnerable Fortigates was published. This list is dated November 2019 and one can only hope that many of these systems have already been patched.

Two days ago, this list was extended with usernames and passwords that were exploted via this vulnerability. Even if the Fortigates have been patched – as long as the passwords have not been changed, an attacker could still use them to gain access to protected networks.

Upgrade your FortiMail now!

There seems to be a vulnerarbility in some FortiMail versions, that allow an unauthenticated remote attacker to access the system by requesting a password change. Please refer to the FortiGuard PSIRT article.

The problem here is not only the unauthorized access to the system, but also the change of the password of all configured administrative accounts. Also, the maintainer functionality to reset the administrator password over a serial console of the FortiMail is being disabled from the attacker.
