An attacker can exploit the update behavior of the WorkTime monitoring daemon to elevate privileges on the local system to NT Authority\SYSTEM. A malicious executable must be named WTWatch.exe and dropped in the C:\ProgramData\wta\ClientExe directory, which is writable by "Everyone". The executable will then be run by the WorkTime monitoring daemon.
