CVE-2026-112357
HighCVSS 7.8Exploitation Probability (EPSS)
Low risk2th percentile - higher than 2% of all known CVEs
Summary
GFI KerioConnect 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.
Risk Assessment
A local non-administrative user can gain SYSTEM privileges, leading to full compromise of the workstation.
Recommendation
Update GFI KerioConnect Outlook Connector to version 10.0.9 Patch 2 or later. Until patched, restrict write access to the product directory.
