CVE-2026-76862

System command manipulation via tcpdump argument injection

Published Sep 15, 2026 · Updated Sep 15, 2026

OS command argument injection in Netcore NR255-V 1.5.130703 allows attackers to manipulate device commands through Nettools tcpdump launch paths. The ntools_start_set_cgi, ntools_tcpdump_start_set_cgi, exe_default, and ntools_proc components pass crafted arguments into tcpdump launch routines without neutralizing command argument delimiters. Public material does not state the required access level or limit the resulting command manipulation to a narrower confidentiality, integrity, or availability impact.
