Senserva AI Opinion for CVE-2018-13382
Fortinet's SSL VPN portal in FortiOS and FortiProxy lets an unauthenticated attacker change a VPN user's password through an improper authorization flaw, no exploit chain required, just a crafted request. Combined with the neighboring FortiOS bugs it gave ransomware crews wholesale access to corporate VPNs, and its 82 percent EPSS score shows sustained abuse. Severity is High at CVSS 7.5.
Do this: Patch FortiOS and FortiProxy, force a password reset for all SSL VPN accounts, and enable MFA on the portal.
