## Affected

- Wertheim GmbH Wertheim SafeController Software for VAULT ROOMS (Safe Deposit Locker System): version range not reported

## Description

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.
