An unauthenticated attacker with physical access to a computer with NetSetMan Pro before 5.0 installed, that has the pre-logon profile switch button within the Windows logon screen enabled, is able to drop to an administrative shell and execute arbitrary commands as SYSTEM via the "save log to file" feature. To accomplish this, the attacker can navigate to cmd.exe.

Security readout for executives and security teams

CVE-2021-34546 lets someone with physical access to a Windows computer gain SYSTEM-level command execution if NetSetMan Pro before 5.0 is installed and its pre-logon profile switch button is enabled. Exposure is limited to Windows systems running NetSetMan Pro before 5.0 with the pre-logon profile switch button enabled. Shared workstations, kiosks, labs, reception devices, and systems in less-controlled physical locations are higher concern. Treat this as a targeted physical-access risk, not an internet-wide emergency. Remediate quickly on public or shared workstations because compromise can grant full local system control. Mitigation focus: Inventory NetSetMan Pro installations and identify versions before 5.0.; Disable the pre-logon profile switch button where it is not required.; Upgrade or remove NetSetMan Pro before 5.0 after confirming vendor guidance..
