CVE-2025-14500Network attack vector

Unauthenticated code execution via unvalidated HTTP header

Published Dec 23, 2025 · Updated Dec 23, 2025

OS command injection in IceWarp Server 14.2.0.5 allows remote attackers to execute arbitrary code through a crafted HTTP header. The X-File-Operation header handler passes an unvalidated user-supplied string into a system call, permitting command injection. No authentication or user interaction is required, and injected commands run in the context of SYSTEM on affected installations.
