description

Fortinet FortiMail versions 8.0.0–8.0.1, 7.6.0–7.6.6, 7.4.0–7.4.8, and 7.2.0–7.2.9 are affected. An unauthenticated remote attacker may place files on the underlying system through the appliance's HTTP or HTTPS service; exposure requires network access to that service.

mitigation

Restrict HTTP and HTTPS access to trusted management networks and block unnecessary external access. No fixed release is identified in the supplied advisory; apply a vendor-provided update when available.
