FortiOS, FortiProxy, and FortiSwitchManager contain a flaw that allows attackers to bypass login requirements and access the admin panel without credentials by sending specially crafted requests. This is critical because admin access can lead to full system compromise.
An authentication bypass vulnerability in Fortinet products (FortiOS 7.0.0–7.0.6, 7.2.0–7.2.1; FortiProxy 7.0.0–7.0.6, 7.2.0; FortiSwitchManager 7.0.0, 7.2.0) allows unauthenticated remote attackers to access the administrative interface via malformed HTTP/HTTPS requests, exploiting CWE-287 (improper authentication). No credentials or pre-authentication are required; successful exploitation grants full administrative privileges.
