TOCTOU Race Condition in SanDisk Dashboard Installer Leads to Privilege Escalation

Executive Summary

This is a time-of-check to time-of-use (TOCTOU) race condition in the Sandisk Dashboard installer. A local, authenticated standard user can replace an installer-staged binary in a user-writable temporary directory between validation and execution. The installer then runs the attacker-controlled binary, leading to local privilege escalation to administrative privileges.
