Authenticated login bypass via spoofed forwarding header
Published Jun 15, 2026 · Updated Jun 15, 2026
IP restriction bypass in Wertheim SafeController Software 6.15.8328.28014 allows remote authenticated users to log in from unapproved networks. The login flow's GetIPAddress method selects the first value in the untrusted HTTP X-Forwarded-For header before falling back to REMOTE_ADDR. Valid branch credentials and knowledge of the branch IP are required; spoofing that value creates an authenticated session outside the permitted location.
