GFI KerioConnect KOFF 10.0.9 Patch 2 之前版本發現本機提權漏洞
CVE-2026-112357 - GFI KerioConnect KOFF < 10.0.9p2 Privilege Escalation
GFI KerioConnect KOFF 10.0.9 Patch 2 之前版本因安裝程式許可權設定錯誤，允許本機非管理者取代 searchd.exe 服務檔，進而以 NT AUTHORITY\SYSTEM 許可權執行任意程式。
本漏洞允許本機非管理者提升至 SYSTEM 許可權，建議立即升級至 10.0.9 Patch 2 以消除高危風險。
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.
