CVE-2026-90847Network attack vector

Remote command execution via iux_set.cgi input

Published Sep 15, 2026 · Updated Sep 15, 2026

OS command injection in EFM Networks ipTIME C200E 1.094 allows remote attackers to execute commands through crafted System Setup requests. An undisclosed function in iux_set.cgi sends manipulated System Setup input to an operating-system command without neutralizing command elements. The CGI endpoint must be network-reachable; public evidence does not establish whether authentication is required or what privileges the injected commands obtain.
