CVE-2026-76866 [HIGH] – Netcore NR255-V firmware version 1.5.130703 builds root-run command lines from unquoted us

Netcore NR255-V firmware version 1.5.130703 builds root-run command lines from unquoted user-supplied DDNS input in DDNSset_cgi.c and related ddns_Proc.c components, enabling os command argument injection. Attackers can exploit the unsanitized parameters to inject additional command arguments executed with root privileges.
