Wertheim GmbH vulnerabilities

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, does not sufficiently validate the branch code when a new branch is created. The branch code is later used in multiple application functions, including filesystem path generation for uploaded files, profile pictures, and settings. An authenticated attacker with the settings_branches_manage privilege can include path traversal sequences in the branch code and influence the final filesystem location used by affected file operations. This can allow files to be stored in unintended locations, subject to service-account write permissions and branch-code length restrictions.

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains a hard-coded cryptographic key in the SafeSystem.Infrastructure.Security.dll component. An attacker with access to the application files can reverse engineer the DLL and recover the hard-coded cryptographic key. This key can be used to decrypt the licence.whs file, which contains sensitive information about the licensing party and a second key that can be used to decrypt other configuration files.

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, exposes web-accessible file paths that are not protected by an authorization scheme. An unauthenticated attacker can directly access HTTP endpoints to download files from locations such as /Resources/CompanyId_[ID]/Audio/ and /SafeData/.

The Wertheim SafeController Software, AssemblyVersion 6.15.8328.28014, contains insufficient server-side file type validation in the /safe/contract/uploadcustomdocuments endpoint. The application validates uploaded files based on the user-controlled HTTP Content-Type value and accepts the upload if this value contains an allowed string such as pdf, jpeg, tiff, or png. An authenticated attacker with any role or permission level can spoof the Content-Type value and upload arbitrary file content.

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.
