Technical details
This vulnerability is a local privilege escalation in Windows Shell stemming from insufficient authentication enforcement on a critical function. The vulnerability requires an authorized local user with valid credentials; it cannot be exploited remotely over the network. By bypassing the missing authentication control, an attacker can elevate their privileges to a higher level (such as SYSTEM or Administrator), gaining full control over the system. A patch is available via Microsoft security updates.
