CVE-2025-64093Network attack vector

Unauthenticated command execution via hostname injection

Published Jan 9, 2026 · Updated Jan 9, 2026

Command injection in Zenitel ICX-500 and ICX-510 before 1.4.3.3 allows remote attackers to execute arbitrary commands via the hostname. The hostname-handling path in a legacy web interface accepts command syntax without neutralizing it before invoking an operating-system command. No authentication or user interaction is required, and successful exploitation gives command execution with the affected device process privileges.
