CVE-2026-19771Public exploitNetwork attack vector

Root command execution via LuCI diagnostic parameters

Published Aug 14, 2026 · Updated Aug 14, 2026

OS command injection in Baicells Photon ID63M EG3661M BaiCE_BQ6_2.0.5.3_NA allows remote authenticated users to execute commands as root. The LuCI diagnosis_route and diagnosis_ping handlers concatenate MaxHops, Timeout, and Size into ping or traceroute shell commands without neutralizing metacharacters. Administrator session tokens and a sysauth cookie are required; a pipe character can append arbitrary BusyBox ash commands, enabling full device control.
