Technical details

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability (CWE-200) exists in the SSL-VPN web-mode component of FortiOS. The flaw is rooted in insufficient access control on specific endpoints, allowing a remote attacker with valid user-level credentials to bypass intended restrictions. By sending a specially crafted URL to the SSL-VPN portal, an authenticated user can retrieve the full SSL-VPN configuration settings. This disclosure could reveal internal network details or security parameters. Fortinet recommends upgrading to FortiOS 7.6.1, 7.4.8, or migrating to a fixed release for older branches.
