BRAdmin Professional 3.75 – ‘BRA_Scheduler’ Unquoted Service Path

This software allows system administrators to view and control the status of their networked Brother and most other SNMP compliant printing devices. If a user can insert a executable which is called as 'BRAdmin' under the 'C:Program Files (x86)Brother', local system privileges could be obtained by the user.

Mitigation:

Ensure that all services have a fully qualified path to the executable, and that the path is enclosed in quotes.
