IP restriction bypass in Wertheim SafeController Software allows logins from unauthorized network locations

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains an IP restriction bypass vulnerability in the login process. The application restricts user logins based on the IP address associated with a branch location, but the client IP address is derived from the HTTP X-Forwarded-For header when that header is present. An attacker with valid branch user credentials can manipulate the X-Forwarded-For header during login to spoof the expected branch IP address and obtain a valid authenticated session from an unauthorized network location.
