CVE-2025-57176Public exploitNetwork attack vector

Unauthenticated arbitrary file upload via unchecked path

Published Sep 15, 2025 · Updated Sep 15, 2025

Unrestricted file upload in Ceragon Siklu EtherHaul and MultiHaul firmware allows remote attackers to write files through TCP port 555. The rfpiped service accepts upload message type 0x04 and uses the supplied destination path without authentication, normalization, or containment validation. Network access to rfpiped is sufficient, and the consequence is bounded to attacker-chosen content in locations writable by the service.
