NVIDIA GeForce Experience contains a vulnerability in the installer, where a user installing the NVIDIA GeForce Experience software may inadvertently delete data from a linked location, which may lead to data tampering. An attacker does not have explicit control over the exploitation of this vulnerability, which requires the user to explicitly launch the installer from the compromised directory.
The product opens a file or directory, but it does not properly prevent the name from being associated with a junction or mount point to a destination that is outside of the intended control sphere.
| Name | Vendor | Start Version | End Version |

Depending on the intended action being performed, this could allow an attacker to cause the product to read, write, delete, or otherwise operate on unauthorized files. In Windows, NTFS5 allows for file system objects called reparse points. Applications can create a hard link from one directory to another directory, called a junction point. They can also create a mapping from a directory to a drive letter, called a mount point. If a file is used by a privileged program, but it can be replaced with a hard link to a sensitive file (e.g., AUTOEXEC.BAT), an attacker could excalate privileges. When the process opens the file, the attacker can assume the privileges of that process, tricking the privileged process to read, modify, or delete the sensitive file, preventing the program from accurately processing data. Note that one can also point to registries and semaphores.
