| Title | Blind remote OS command injection in Host Name on TOTOLink EX1200L |
|---|
| Description | ## Description and impact
Function `setWanCfg` executes os command `echo` to overwrite hostname. An attacker can execute remote os command using crafted payload at `Host Name`.
## Root-cause
When the function `setWanCfg` is called, it crafts os command following syntax `echo '%s' > /proc/sys/kernel/hostname`. The value of `Host name` is not validated. An attacker can send crafted payload to execute OS command.
