Lenovo Preload Directory Vulnerability
Lenovo Security Advisory: LEN-127385
Potential Impact: Privilege Escalation
Severity: High
Scope of Impact: Lenovo-specific
CVE Identifier: CVE-2023-4706
Summary Description:
A privilege escalation vulnerability was reported in Lenovo preloaded devices deployed using Microsoft AutoPilot under a standard user account due to incorrect default privileges.
Due to a potential conflict between Microsoft Out of Box Experience (OOBE) and Microsoft Autopilot, the Lenovo preloaded OOBE RunOnce registry keys are suppressed, preventing the removal of the "C:\Windows\1Lenovo" directory containing the OOBE scripts.
Mitigation Strategy for Customers (what you should do to protect yourself):
If affected by this vulnerability, Lenovo recommends deleting the following RunOnce registry keys and the directory containing OOBE scripts:
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\Unattend0000000020{BE2A706E-7924-4DA2-AD2A-E4F9AEFCBC62}
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce\Unattend0000000089{492519C1-9AD9-4681-8B35-60034A80F877}
C:\Windows\1Lenovo
