NetSetMan 4.7.1 Workgroup Buffer Overflow Denial of Service

NetSetMan 4.7.1 contains a buffer overflow vulnerability in the Workgroup feature that allows local attackers to crash the application by supplying oversized input. Attackers can create a malicious configuration file with excessive data and paste it into the Workgroup field to trigger a denial of service condition.

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.
