CVE-2026-2194Public exploitNetwork attack vector

Authenticated command execution via unescaped NVRAM values

Published Feb 8, 2026 · Updated Feb 8, 2026

Command injection in D-Link DI-7100G C1 24.04.18D1 allows remote authenticated users to execute arbitrary system commands. The start_proxy_client_email function inserts ac_mng_srv_host and other NVRAM values into an snprintf-built pro_cli_ema.sh command without filtering or escaping, then passes it to jhl_system. Remote authenticated users must modify the relevant configuration fields; execution occurs at device startup or when the proxy client email function is triggered, enabling control of the appliance.
