Description
GFI KerioConnect (Kerio Connect) Outlook Connector (Offline Edition), 'KOFF', before 10.0.9 Patch 2 contains a local privilege escalation vulnerability caused by weak installer permissions that leave the product directory writable by the built-in Users group. A local non-administrative attacker can replace the searchd.exe service binary used by the bundled KOFFIndexingService, which runs as LocalSystem, to execute arbitrary code with NT AUTHORITY\SYSTEM privileges upon the next service start or reboot.
