Published Jul 8, 2024 · Updated Nov 4, 2025

Command injection in LevelOne WBR-6013 RER4_A_v3411b_2T2R_LEV_09_170623 allows remote authenticated users to execute arbitrary commands. The boa formSysCmd handler reads the sysCmd request parameter, formats it into a shell command with sprintf, and passes the result to system(). Administrative credentials and network access to the web interface are required; submitted commands run on the router and can reboot it.
