Tauri is a framework for building binaries for all major desktop platforms. In versions prior to 1.0.7 and 1.1.2, Tauri is vulnerable to an Incorrectly-Resolved Name. Due to incorrect escaping of special characters in paths selected via the file dialog and drag and drop functionality, it is possible to partially bypass the fs scope definition. It is not possible to traverse into arbitrary paths, as the issue is limited to neighboring files and sub folders of already allowed paths. The impact differs on Windows, MacOS and Linux due to different specifications of valid path characters. This bypass depends on the file picker dialog or dragged files, as user selected paths are automatically added to the allow list at runtime. A successful bypass requires the user to select a pre-existing malicious file or directory during the file picker dialog and an adversary controlled logic to access these files. The issue has been patched in versions 1.0.7, 1.1.2 and 1.2.0. As a workaround, disable the dialog and fileDropEnabled component inside the tauri.conf.json.

Weakness

The product exposes a resource to the wrong control sphere, providing unintended actors with inappropriate access to the resource.

Extended Description

Resources such as files and directories may be inadvertently exposed through mechanisms such as insecure permissions, or when a program accidentally operates on the wrong object. For example, a program may intend that private files can only be provided to a specific user. This effectively defines a control sphere that is intended to prevent attackers from accessing these private files. If the file permissions are insecure, then parties other than the user will be able to access those files. A separate control sphere might effectively require that the user can only access the private files, but not any other files on the system. If the program does not ensure that the user is only requesting private files, then the user might be able to access other files on the system. In either case, the end result is that a resource has been exposed to the wrong party.
